This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malicious JavaScript woulhttps://patchthecve.com/cve/CVE-2026-23927.htmlhttps://patchthecve.com/cve/CVE-2026-23927.htmlFri, 18 Sep 2026 15:26:56 +0000MEDIUM 6.5: 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.https://patchthecve.com/cve/CVE-2026-23926.htmlhttps://patchthecve.com/cve/CVE-2026-23926.htmlFri, 18 Sep 2026 15:35:11 +0000MEDIUM 6.8: 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 thehttps://patchthecve.com/cve/CVE-2026-23924.htmlhttps://patchthecve.com/cve/CVE-2026-23924.htmlFri, 18 Sep 2026 17:02:40 +0000MEDIUM 4.9: 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.https://patchthecve.com/cve/CVE-2026-23923.htmlhttps://patchthecve.com/cve/CVE-2026-23923.htmlThu, 10 Sep 2026 21:16:44 +0000MEDIUM 5.3: An unauthenticated attacker can exploit the Frontend 'validate' action to blindly instantiate arbitrary PHP classes. The impact depends on environment setup but appears limited at this time.https://patchthecve.com/cve/CVE-2026-23921.htmlhttps://patchthecve.com/cve/CVE-2026-23921.htmlThu, 10 Sep 2026 21:13:20 +0000HIGH 8.8: 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 throughttps://patchthecve.com/cve/CVE-2026-23920.htmlhttps://patchthecve.com/cve/CVE-2026-23920.htmlThu, 10 Sep 2026 21:15:39 +0000HIGH 8.8: 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.https://patchthecve.com/cve/CVE-2026-23919.htmlhttps://patchthecve.com/cve/CVE-2026-23919.htmlFri, 18 Sep 2026 17:07:18 +0000MEDIUM 6.0: 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
