A database whose name is such a string, which any role with CREATEDB can create, therefore redirected the psql process pgAdmin starts for the refresh to a host and port of the creator\u0027s choosing, and the connecting user\u0027s saved server password was presented to that endpoint. It also let the pgAdmin host be made to open connections to arbitrary addresses.\n\nThe same weakness was fixed for Backup, Restore, Maintenance and Import/Export Data in earlier releases (CVE-2026-86862); the materialized view refresh was the remaining caller. The fix routes the name through the same database_conninfo() helper, so libpq treats it strictly as a database name.\n\nThis issue affects pgAdmin 4: before 9.19."

A session established before the change, for example on another device or by someone who had obtained the old password or a session cookie, therefore stayed logged in after the change, which is the step a user or administrator takes precisely to cut such access off. It remained usable until it expired.\n\nThe fix rotates the user\u0027s session identifier (fs_uniquifier) whenever the password is changed, so every other session of that user is logged out. The session that made the change is logged in again and keeps its database connections. Saved server passwords, including those for shared servers, are re-encrypted under the new key; any that cannot be decrypted are cleared and the user is told. If re-encryption fails, the sessions are still revoked and the saved passwords are cleared rather than the change failing.\n\nThis issue affects pgAdmin 4: before 9.19."

On Windows, SSPI used the service account\u0027s logon in the same way. psql was also started with pgAdmin\u0027s environment, which could hold another user\u0027s credential cache while that user was connecting.\n\nThe fix points KRB5CCNAME and KRB5_CLIENT_KTNAME at a file that cannot exist except while a Kerberos-authenticated user connects with Kerberos, and gives every other connection, psql and the utilities require_auth=!gss,!sspi and gssencmode=disable, checked on the final connection string. require_auth needs libpq 16 or later.\n\nThis issue affects pgAdmin 4: before 9.19."

A user could therefore upload an executable to shared storage, point their binary path at it, and have pgAdmin run it as the operating-system account running pgAdmin. On POSIX, files created through pgAdmin are not executable, so this is exploitable where any file with an executable name can run, such as Windows server mode.\n\nThe fix checks the binary path against every SHARED_STORAGE directory as well, after expanding $DIR, collapsing \"..\" and resolving symbolic links, compares directories in a way a different spelling on a case-insensitive filesystem cannot bypass, refuses a path containing a NUL, and enforces the check wherever binary paths are resolved, including for the PSQL tool.\n\nThis issue affects pgAdmin 4: before 9.19."

The check rejected a backslash inside a single-quoted string, but not inside a double-quoted identifier, where it treated the next double quote as closing the identifier. psql\u0027s \\copy parser applies the connection\u0027s escape character to whichever quote opened a token, so with standard_conforming_strings off a backslash-escaped double quote does not close the identifier. pgAdmin\u0027s and psql\u0027s view of the quoting then diverged, a closing parenthesis hidden from the check ended the \\copy (...) wrapper, and a following TO PROGRAM clause was executed by psql on the pgAdmin host, as the operating-system account running pgAdmin, before the server rejected the statement. An ordinary database role can turn standard_conforming_strings off for itself, and the Import/Export Data permission is granted to non-administrators by default.\n\nThis is a bypass of the fix for CVE-2026-17566. The fix rejects any backslash inside a double-quoted identifier, as was already done for single-quoted strings, since its meaning depends on a server setting that cannot be known reliably when the query is validated.\n\nThis issue affects pgAdmin 4: before 9.19."

On POSIX a path checked as a name inside storage could become an absolute path once stripped, so any file the pgAdmin account can read could be opened; on Windows a path naming a drive discarded the storage directory, so these could read, or write, outside it.\n- Listing a folder decoded the path a second time after the check, so a folder named like an encoded \"..\", which a user can create, listed any directory on the host.\n- Download, delete, rename and the file-exists check appended the path to the storage directory without a separator, so in a deployment where one user\u0027s storage directory name is a prefix of another\u0027s, another user\u0027s files could be read, deleted or moved; download also checked the path appended to itself.\n- Creating a folder could create one in another user\u0027s directory.\n\nThe fix makes check_access_permission() return the path it checked and every caller act on that path, decodes folder paths once, and opens, deletes and renames files relative to directories opened from the storage directory without following symbolic links.

Because pg_dump parses its options with getopt_long, which permutes arguments, a value beginning with a dash was interpreted as an option rather than as a database name. A value such as --file=/absolute/path therefore overrode the storage-confined --file that pgAdmin had constructed earlier, causing pg_dump to write its output anywhere the pgAdmin process could write, outside the user\u0027s File Manager storage directory. This yields arbitrary file creation and overwrite as the operating-system account running pgAdmin, which can destroy pgAdmin\u0027s own configuration database and, depending on the target chosen, be escalated further.\n\nThe same field additionally permitted connection-string injection. libpq expands a database name containing an equals sign into a full connection string, and keywords embedded there override the --host and --port that pgAdmin passes, so a value such as \u0027host=attacker.example port=5432 dbname=x\u0027 redirected pg_dump to a server of the attacker\u0027s choosing. Because pgAdmin exports the decrypted stored database password in the PGPASSWORD environment variable before executing the utility, the redirected connection carries that credential to the attacker-nominated endpoint. Both behaviours are reachable by any authenticated user holding the tools_backup permission, which is granted to the default User role.\n\nThe fix stops passing the database name through the argument vector altogether and supplies it in the PGDATABASE environment variable, which libpq treats as a literal database name and never expands as a connection string. This matches the approach already used by the Import/Export tool. Regression tests assert that the database name is absent from the constructed argument vector and that PGDATABASE carries the exact requested value.\n\nThis issue affects pgAdmin 4: from the introduction of the trailing positional database argument in the Backup tool before 9.18."

WebserverAuthentication.get_user() read config.WEBSERVER_REMOTE_USER from request.environ and, when that returned nothing, fell back to reading the same name directly from the inbound HTTP request headers via request.headers.get(). An inbound HTTP header is written by whoever sends the request, so any client able to reach pgAdmin could supply that header itself and be authenticated as any username it named, including an existing Administrator, without presenting a password or any other credential. The environment lookup could also be satisfied by a client-supplied header whenever WEBSERVER_REMOTE_USER was configured to an HTTP_-prefixed or hyphenated name such as HTTP_X_FORWARDED_USER or X-Forwarded-User, since WSGI servers place inbound headers into the environment under exactly those names. Deployments are affected only when \u0027webserver\u0027 is enabled in AUTHENTICATION_SOURCES.\n\nThe fix distinguishes a genuine CGI/WSGI variable from a header-derived one and implicitly trusts only the former. A header-asserted identity is now accepted only when the operator explicitly opts in via WEBSERVER_REMOTE_USER_FROM_HEADER, the request arrives from a peer listed in WEBSERVER_TRUSTED_PROXIES, and, when configured, a shared secret supplied in WEBSERVER_SHARED_SECRET_HEADER matches WEBSERVER_SHARED_SECRET under a constant-time comparison. The trusted-peer check deliberately reads the real socket peer address rather than request.remote_addr, because ProxyFix rewrites the latter from the client-controlled X-Forwarded-For header and would otherwise allow an attacker to claim to be the trusted proxy. As defence in depth, login() now refuses any account whose auth_source is not \u0027webserver\u0027, so a misconfigured trust gate cannot be used to assume an internal or LDAP account.\n\nThis issue affects pgAdmin 4: from 6.2 before 9.18."

A value such as \u0027host=attacker.example port=5432 dbname=x\u0027 therefore redirected the utility to a server chosen by the requesting user rather than the server the operation was invoked against. Because pgAdmin exports the decrypted stored database password in the PGPASSWORD environment variable before executing the utility, the redirected connection presents that credential to the attacker-nominated endpoint, which may capture it. The redirection additionally permits outbound connections from the pgAdmin host to arbitrary network addresses, including hosts not otherwise reachable by the requesting user.\n\nThe behaviour is reachable by any authenticated user holding the tools_restore or tools_maintenance permission, both of which the default User role grants. The Maintenance tool was not affected in the earliest releases, where the value was wrapped by a quoting helper that incidentally prevented expansion; it became affected when that wrapper was removed.\n\nThe fix supplies the target database in the PGDATABASE environment variable, which libpq treats as a literal database name and never expands as a connection string. Where pg_restore requires a --dbname argument to be present, an empty value is passed, which contains no equals sign and is therefore not expanded, while the real name is taken from the environment.\n\nThis issue affects pgAdmin 4: from the introduction of the --dbname argument in the Restore and Maintenance tools before 9.18."

CVE-2026-7819 had previously hardened the separate file upload path by opening its target with O_NOFOLLOW, so that the kernel refuses to follow a symbolic link at the final path component, but save_file was left on an unprotected open(). A symbolic link already present when the check ran was rejected by the check itself; the remaining exposure was a link substituted at the final path component in the interval between the check and the write, at which point the write followed the link and landed outside the user\u0027s storage directory, creating or overwriting an arbitrary file as the operating-system account running pgAdmin.\n\nExploitation requires the ability to create or replace a symbolic link inside the requesting user\u0027s storage directory. pgAdmin exposes no interface that creates symbolic links, so this requires filesystem access to the pgAdmin host or to a shared or network-mounted storage backend, together with winning the timing window. The reporter did not achieve a write against a released version, having attempted approximately 63,000 racing requests without success; the reported defect is the uncovered write path rather than a demonstrated sandbox escape.\n\nThe fix routes save_file\u0027s write through the same O_NOFOLLOW-protected helper already used by the upload path, so both File Manager write sinks carry identical kernel-enforced protection, and reports a symbolic-link refusal explicitly instead of surfacing the underlying system error text. Note that files created by save_file are now given mode 0600, inheriting the behaviour introduced for uploads. The protection covers the final path component; substitution of an intermediate directory component is not addressed by this change.\n\nThis issue affects pgAdmin 4: from the introduction of the containment check in the File Manager save path before 9.18."

In server mode any user could therefore connect to a server with the service account\u0027s saved passwords or client certificate, and supplying only a copy of its public certificate was enough for libpq to pair it with the service account\u0027s private key. A pg_service.conf entry, or a maintenance database name read as a connection string by pg_dumpall, could bring the same files back for the utilities.\n\nThe fix gives each of these parameters a value in server mode, the user\u0027s own file or otherwise a path that can never be opened, in the connection string, in the environment of the utilities and in the --dbname connection string that ranks above a service entry. Desktop mode is unchanged.\n\nThis issue affects pgAdmin 4: before 9.19."

In server mode any user could therefore configure a tunnel to a host that accepts the service account\u0027s key, with no credentials of their own or with an identity file that did not exist in their storage, and reach it as that account.\n\nThe fix makes tunnels in server mode use only the identity file or password the user configured: the service account\u0027s keys, configuration and agent are no longer used, and an identity file that cannot be found in the user\u0027s storage is reported instead of falling back to ~/.ssh.

The check rejected a backslash inside a single-quoted string, but not inside a double-quoted identifier, where it treated the next double quote as closing the identifier. psql\u0027s \\copy parser applies the connection\u0027s escape character to whichever quote opened a token, so with standard_conforming_strings off a backslash-escaped double quote does not close the identifier. pgAdmin\u0027s and psql\u0027s view of the quoting then diverged, a closing parenthesis hidden from the check ended the \\copy (...) wrapper, and a following TO PROGRAM clause was executed by psql on the pgAdmin host, as the operating-system account running pgAdmin, before the server rejected the statement. An ordinary database role can turn standard_conforming_strings off for itself, and the Import/Export Data permission is granted to non-administrators by default.\n\nThis is a bypass of the fix for CVE-2026-17566.

On POSIX a path checked as a name inside storage could become an absolute path once stripped, so any file the pgAdmin account can read could be opened; on Windows a path naming a drive discarded the storage directory, so these could read, or write, outside it.\n- Listing a folder decoded the path a second time after the check, so a folder named like an encoded \"..\", which a user can create, listed any directory on the host.\n- Download, delete, rename and the file-exists check appended the path to the storage directory without a separator, so in a deployment where one user\u0027s storage directory name is a prefix of another\u0027s, another user\u0027s files could be read, deleted or moved; download also checked the path appended to itself.\n- Creating a folder could create one in another user\u0027s directory.\n\nThe fix makes check_access_permission() return the path it checked and every caller act on that path, decodes folder paths once, and opens, deletes and renames files relative to directories opened from the storage directory without following symbolic links.

Because pg_dump parses its options with getopt_long, which permutes arguments, a value beginning with a dash was interpreted as an option rather than as a database name. A value such as --file=/absolute/path therefore overrode the storage-confined --file that pgAdmin had constructed earlier, causing pg_dump to write its output anywhere the pgAdmin process could write, outside the user\u0027s File Manager storage directory. This yields arbitrary file creation and overwrite as the operating-system account running pgAdmin, which can destroy pgAdmin\u0027s own configuration database and, depending on the target chosen, be escalated further.\n\nThe same field additionally permitted connection-string injection. libpq expands a database name containing an equals sign into a full connection string, and keywords embedded there override the --host and --port that pgAdmin passes, so a value such as \u0027host=attacker.example port=5432 dbname=x\u0027 redirected pg_dump to a server of the attacker\u0027s choosing. Because pgAdmin exports the decrypted stored database password in the PGPASSWORD environment variable before executing the utility, the redirected connection carries that credential to the attacker-nominated endpoint. Both behaviours are reachable by any authenticated user holding the tools_backup permission, which is granted to the default User role.\n\nThe fix stops passing the database name through the argument vector altogether and supplies it in the PGDATABASE environment variable, which libpq treats as a literal database name and never expands as a connection string. This matches the approach already used by the Import/Export tool. Regression tests assert that the database name is absent from the constructed argument vector and that PGDATABASE carries the exact requested value.\n\nThis issue affects pgAdmin 4: from the introduction of the trailing positional database argument in the Backup tool before 9.18."

WebserverAuthentication.get_user() read config.WEBSERVER_REMOTE_USER from request.environ and, when that returned nothing, fell back to reading the same name directly from the inbound HTTP request headers via request.headers.get(). An inbound HTTP header is written by whoever sends the request, so any client able to reach pgAdmin could supply that header itself and be authenticated as any username it named, including an existing Administrator, without presenting a password or any other credential. The environment lookup could also be satisfied by a client-supplied header whenever WEBSERVER_REMOTE_USER was configured to an HTTP_-prefixed or hyphenated name such as HTTP_X_FORWARDED_USER or X-Forwarded-User, since WSGI servers place inbound headers into the environment under exactly those names. Deployments are affected only when \u0027webserver\u0027 is enabled in AUTHENTICATION_SOURCES.\n\nThe fix distinguishes a genuine CGI/WSGI variable from a header-derived one and implicitly trusts only the former. A header-asserted identity is now accepted only when the operator explicitly opts in via WEBSERVER_REMOTE_USER_FROM_HEADER, the request arrives from a peer listed in WEBSERVER_TRUSTED_PROXIES, and, when configured, a shared secret supplied in WEBSERVER_SHARED_SECRET_HEADER matches WEBSERVER_SHARED_SECRET under a constant-time comparison. The trusted-peer check deliberately reads the real socket peer address rather than request.remote_addr, because ProxyFix rewrites the latter from the client-controlled X-Forwarded-For header and would otherwise allow an attacker to claim to be the trusted proxy. As defence in depth, login() now refuses any account whose auth_source is not \u0027webserver\u0027, so a misconfigured trust gate cannot be used to assume an internal or LDAP account.\n\nThis issue affects pgAdmin 4: from 6.2 before 9.18."

A value such as \u0027host=attacker.example port=5432 dbname=x\u0027 therefore redirected the utility to a server chosen by the requesting user rather than the server the operation was invoked against. Because pgAdmin exports the decrypted stored database password in the PGPASSWORD environment variable before executing the utility, the redirected connection presents that credential to the attacker-nominated endpoint, which may capture it. The redirection additionally permits outbound connections from the pgAdmin host to arbitrary network addresses, including hosts not otherwise reachable by the requesting user.\n\nThe behaviour is reachable by any authenticated user holding the tools_restore or tools_maintenance permission, both of which the default User role grants. The Maintenance tool was not affected in the earliest releases, where the value was wrapped by a quoting helper that incidentally prevented expansion; it became affected when that wrapper was removed.\n\nThe fix supplies the target database in the PGDATABASE environment variable, which libpq treats as a literal database name and never expands as a connection string. Where pg_restore requires a --dbname argument to be present, an empty value is passed, which contains no equals sign and is therefore not expanded, while the real name is taken from the environment.\n\nThis issue affects pgAdmin 4: from the introduction of the --dbname argument in the Restore and Maintenance tools before 9.18."

CVE-2026-7819 had previously hardened the separate file upload path by opening its target with O_NOFOLLOW, so that the kernel refuses to follow a symbolic link at the final path component, but save_file was left on an unprotected open(). A symbolic link already present when the check ran was rejected by the check itself; the remaining exposure was a link substituted at the final path component in the interval between the check and the write, at which point the write followed the link and landed outside the user\u0027s storage directory, creating or overwriting an arbitrary file as the operating-system account running pgAdmin.\n\nExploitation requires the ability to create or replace a symbolic link inside the requesting user\u0027s storage directory. pgAdmin exposes no interface that creates symbolic links, so this requires filesystem access to the pgAdmin host or to a shared or network-mounted storage backend, together with winning the timing window. The reporter did not achieve a write against a released version, having attempted approximately 63,000 racing requests without success; the reported defect is the uncovered write path rather than a demonstrated sandbox escape.\n\nThe fix routes save_file\u0027s write through the same O_NOFOLLOW-protected helper already used by the upload path, so both File Manager write sinks carry identical kernel-enforced protection, and reports a symbolic-link refusal explicitly instead of surfacing the underlying system error text. Note that files created by save_file are now given mode 0600, inheriting the behaviour introduced for uploads. The protection covers the final path component; substitution of an intermediate directory component is not addressed by this change.\n\nThis issue affects pgAdmin 4: from the introduction of the containment check in the File Manager save path before 9.18."
