CVE-2026-24891Public exploitNetwork attack vector

Code execution via unsafe Gearman job deserialization

Published Feb 20, 2026 · Updated Feb 20, 2026

Unsafe deserialization in openITCOCKPIT before 5.4.0 allows remote attackers to execute code through crafted Gearman job payloads. The oitc_gearman worker passes each job payload directly to PHP unserialize() without source validation or class restrictions. Exploitation requires an untrusted system to enqueue jobs through an exposed or unrestricted Gearman service and runs gadget-chain code with worker privileges.
