CVE-2026-24891 is an unsafe deserialization vulnerability affecting openITCOCKPIT versions 5.3.1 and below. The Gearman worker implementation improperly deserializes job payloads, allowing for PHP Object Injection. This vulnerability carries a CVSS score of 7.5 (HIGH), indicating that an attacker with low privileges can achieve high impact on confidentiality, integrity, and availability, though with high attack complexity. While not actively exploited in the wild, nor having public exploit code or significant community discussion, the underlying unsafe deserialization sink remains present and exploitable in misconfigured environments where Gearman is exposed to untrusted systems.
