Title
PostgreSQL ECPG integer underflow can crash the client
Summary
Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside attacker knowledge or control. This typically yields a simple SIGSEGV, but rare cases might achieve client-specific integrity impact via the write. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

PostgreSQL ascii() function reads past end of buffer
Summary
Buffer over-read in PostgreSQL ascii() SQL function allows a user to disclose up to 3 bytes after the end of a specific allocation, via a crafted text value. This is the same class of defect that CVE-2026-2006 fixed, though this instance has less impact. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Title
PostgreSQL psql \unrestrict lets superuser of pg_dump origin server execute arbitrary code in psql client
Summary
Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql \restrict meta-command input expansion. The fix for CVE-2025-8714 introduced \restrict and \unrestrict to block this attack, but \unrestrict itself was sufficient for an attack. pg_dumpall is also affected. pg_restore is affected when used to generate a plain-format dump. Non-core use of \restrict would be affected, but we've not identified non-core use. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Title
PostgreSQL psql COPY FROM STDIN early failure processes data lines as psql commands
Summary
Untrusted data inclusion in PostgreSQL psql COPY may allow a server administrator to elicit execution of data lines as psql commands, via error injection. If the "COPY FROM STDIN" or "\copy FROM STDIN" command fails before the server indicates that it awaits input rows, psql processes the in-line data rows as psql commands. "COPY FROM" with a filename is unaffected. The server administrator has no inherent control over the data rows, so a complete attack requires the attacker to separately acquire control of both the server and the data rows. Alternatively, an attacker controlling data rows alone might complete an attack through a coincidental error that they don't control. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Title
PostgreSQL ALTER TABLE ALTER TYPE resets extended statistics ownership
Summary
Incorrect ownership assignment in PostgreSQL ALTER TABLE ALTER TYPE command reassigns ownership of dependent statistics objects to the current user. This wrongly allows the table owner to run DROP STATISTICS and ALTER STATISTICS via this improper ownership. It wrongly denies those commands to the prior statistics object owner. DROP TABLE remains able to remove statistics objects, so this exploit achieves nothing in many ownership arrangements. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Title
PostgreSQL fails to check type USAGE privilege
Summary
Missing authorization in PostgreSQL DDL commands allows an object creator to achieve denial of service against ALTER and DROP of the type, via creating a dependency on the type. Many DDL operations did check the privilege, but assigning a range subtype and referencing the type from an SQL expression did not. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Title
PostgreSQL logical decoding can dlopen arbitrary file
Summary
Missing authorization in PostgreSQL logical decoding allows a non-superuser holding REPLICATION privilege to dlopen any file visible to the operating system account running the server, via the choice of logical decoding plugin. This in turn runs arbitrary code as that account. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
