CVE-2026-59788 (GCVE-0-2026-59788)

Title
Stored XSS vulnerability in OAuth configuration form
Summary
The email media type OAuth form passes the Authorization endpoint value to window.open() without validating the URL scheme, so a javascript: URL is executed in the browser. This means a crafted media type configuration, deliverable as an import file, runs arbitrary JavaScript as the Super Admin who grants consent.

Title
SNMP trap injection in zabbix_trap_receiver.pl
Summary
The Perl SNMP trap receiver script shipped with Zabbix does not properly neutralize the ZBXTRAP record delimiter in trap content. This means someone able to send SNMP traps can inject a record targeting another host, resulting in a loss of integrity.

Active agent heartbeat missing TLS check
Summary
Zabbix Server and Proxy accept the active agent heartbeat message regardless of the configured PSK or certificate authentication. This means someone with access to the Zabbix trapper port can report an arbitrary host using an active agent as available, resulting in a loss of integrity.

Hidden host credentials inferable via multiselect.get filtering
Summary
Host search in Frontend allows filtering by fields that are not displayed, including stored IPMI and PSK credentials. A user with read access can guess a credential and see from the search result whether the guess was right, letting them uncover it.

Title
Improper validation of custom installation directories on Windows could allow installation into locations with unsafe permissions, increasing the risk of DLL sideloading.
Summary
When Zabbix Agent was installed on Windows into a custom installation directory, the installer did not verify whether the selected directory had secure access permissions. If the target directory allowed unauthorized users to modify its contents, an attacker could place a malicious DLL that could later be loaded by the application, resulting in DLL sideloading. The installer has been hardened to detect potentially unsafe installation directories and now requires explicit user confirmation before proceeding with installation in such locations. This reduces the risk of accidental installation into directories with inappropriate permissions while preserving compatibility with existing deployment scenarios.

CVE-2026-23933 (GCVE-0-2026-23933)

Title
Hardcoded session key in Zabbix 7.4
Summary
In Zabbix 7.4 the cryptographic key used for signing Frontend sessions has been erroneously written to the database seed. Currently the only known exploitation scenario is for deployments that utilize both - SAML authentication and guest users. In such cases the key can be used to forge valid session cookies, potentially leading to unauthorized access. For other Zabbix deployments this does not have a known impact.

Title
Stored XSS vulnerability in the Item history/Plain text widget
Summary
The Item history widget (in Zabbix 7.0+) or the Plain text widget (in Zabbix 6.0) can execute injected JavaScript when HTML display is enabled. This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malicious JavaScript would have to come from a monitored host controlled by the attacker. Note: the Item history widget is a replacement for the Plain text widget since Zabbix 7.0.

Title
Agent 2 Oracle plugin TNS connection string injection via the 'service' parameter
Summary
A user able to connect to Agent 2 can inject an Oracle TNS connection string via the 'service' parameter. This can lead to Agent 2 connecting to an attacker-controlled server and leaking Oracle database credentials if they are saved in a named session.

Title
Blind, read-only SQL injection in Zabbix API via sortfield parameter
Summary
A low privilege Zabbix user with API access can exploit a blind SQL injection vulnerability in include/classes/api/CApiService.php to execute arbitrary SQL selects via the sortfield parameter. Although query results are not returned directly, an attacker can exfiltrate arbitrary database data through time-based techniques, potentially leading to session identifier disclosure and administrator account compromise.

Title
Host and event action script regex validation can be bypassed in certain situations, leading to potential command injection
Summary
Host and event action script input is validated with a regex (set by the administrator), but the validation runs in multiline mode. If ^ and $ anchors are used in user input validation, an injected newline lets authenticated users bypass the check and inject shell commands.

Title
Insufficient isolation of JavaScript (Duktape) execution context on Zabbix Server
Summary
For performance reasons Zabbix Server/Proxy reuses JavaScript (Duktape) contexts (used in script items, JavaScript reprocessing, Webhooks). This can lead to confidentiality loss where a regular (non-super) Zabbix administrator leaks data for hosts they do not have access to. A fix has been released that makes the built in Zabbix JavaScript objects read-only, but please be advised that usage of global JavaScript variables is not recommended because their content could be leaked. More information <a href='https://www.zabbix.com/documentation/7.4/en/manual/installation/known_issues#preprocessing-global-variables-are-unsafe'>in Zabbix documentation</a>.

Title
Unauthorized host creation via configuration.import API by low-privilege user with write permissions
Summary
An authenticated Zabbix user (User role) with template/host write permissions is able to create objects via the configuration.import API. This can lead to confidentiality loss by creating unauthorized hosts. Note that the User role is normally not sufficient to create and edit templates/hosts even with write permissions.
