  1. CVE-2026-23928

    Hoch · CVSS 7.3EPSS 0,26%Keine Korrektur veröffentlicht

    Stored XSS vulnerability in the Item history/Plain text widget

    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.

    Agent 2 Oracle plugin TNS connection string injection via the 'service' parameter

    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.

  3. CVE-2026-23926

    Hoch · CVSS 7.3EPSS 0,26%Keine Korrektur veröffentlicht

    Stored XSS vulnerability in Host navigator widget maintenance tooltip

    An authenticated (non-super) administrator can create a maintenance period with a JavaScript payload that is executed by any user that opens tooltip for that maintenance period in the Host navigator widget. This can allow the attacker to perform unauthorized actions depending on which user opens the tooltip.

    Mittel · CVSS 6.1EPSS 0,24%Keine Korrektur veröffentlicht

    Agent 2 Docker plugin arbitrary file read via Docker API injection

    Zabbix Agent 2 Docker plugin does not properly sanitize the 'docker.container_info' parameters when forwarding them to the Docker daemon. An attacker capable of invoking Agent 2 can read arbitrary files from running Docker containers by injecting them via the Docker archive API.

    Hoch · CVSS 8.7EPSS 4,1%Öffentlicher ExploitKeine Korrektur veröffentlicht

    Blind, read-only SQL injection in Zabbix API via sortfield parameter

    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.

  6. CVE-2026-23920

    Hoch · CVSS 7.7EPSS 0,31%Keine Korrektur veröffentlicht

    Host and event action script regex validation can be bypassed in certain situations, leading to potential command injection

    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.

  7. CVE-2026-23919

    Hoch · CVSS 7.1EPSS 0,26%Keine Korrektur veröffentlicht

    Insufficient isolation of JavaScript (Duktape) execution context on Zabbix Server

    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.

  8. CVE-2026-23925

    Mittel · CVSS 5.1EPSS 0,27%Keine Korrektur veröffentlicht

    Unauthorized host creation via configuration.import API by low-privilege user with write permissions

    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.

  9. CVE-2025-49643

    Mittel · CVSS 6EPSS 0,34%Keine Korrektur veröffentlicht

    Frontend DoS vulnerability due to asymmetric resource consumption

    An authenticated Zabbix user (including Guest) is able to cause disproportionate CPU load on the webserver by sending specially crafted parameters to /imgstore.php, leading to potential denial of service.

  10. CVE-2025-49641

    Mittel · CVSS 5.1EPSS 0,3%Keine Korrektur veröffentlicht

    Insufficient permission check for the problem.view.refresh action

    A regular Zabbix user with no permission to the Monitoring -> Problems view is still able to call the problem.view.refresh action and therefore still retrieve a list of active problems.

    Niedrig · CVSS 2.1EPSS 0,38%Keine Korrektur veröffentlicht

    User information disclosure via api_jsonrpc.php on method user.get with param search

    A regular Zabbix user can search other users in their user group via Zabbix API by select fields the user does not have access to view. This allows data-mining some field values the user does not have access to.

    LDAP 'Bind password' field value can be leaked by a Zabbix Super Admin

    The LDAP 'Bind password' value cannot be read after saving, but a Super Admin account can leak it by changing LDAP 'Host' to a rogue LDAP server. To mitigate this, the 'Bind password' value is now reset on 'Host' change.

  13. CVE-2025-27233

    Mittel · CVSS 5.7EPSS 0,17%Keine Korrektur veröffentlicht

    Zabbix Agent 2 smartctl plugin argument injection in Zabbix 6.0 and later.

    Zabbix Agent 2 smartctl plugin does not properly sanitize smart.disk.get parameters, allowing an attacker to inject unexpected arguments into the smartctl command. This can be used to leak the NTLMv2 hash from a Windows system.

  14. CVE-2024-45700

    Mittel · CVSS 6EPSS 0,36%Keine Korrektur veröffentlicht

    DoS vulnerability due to uncontrolled resource exhaustion

    Zabbix server is vulnerable to a DoS vulnerability due to uncontrolled resource exhaustion. An attacker can send specially crafted requests to the server, which will cause the server to allocate an excessive amount of memory and perform CPU-intensive decompression operations, ultimately leading to a service crash.

  15. CVE-2024-45699

    Hoch · CVSS 7.5EPSS 0,36%Keine Korrektur veröffentlicht

    Reflected XSS vulnerability in /zabbix.php?action=export.valuemaps

    The endpoint /zabbix.php?action=export.valuemaps suffers from a Cross-Site Scripting vulnerability via the backurl parameter. This is caused by the reflection of user-supplied data without appropriate HTML escaping or output encoding. As a result, a JavaScript payload may be injected into the above endpoint causing it to be executed within the context of the victim's browser.
