CVE-2026-24892Public exploitNetwork attack vector

Latent object injection via unrestricted changelog deserialization

Published Feb 20, 2026 · Updated Feb 20, 2026

Unsafe deserialization in openITCOCKPIT Community Edition 5.3.1 and earlier creates a latent PHP object-injection sink in changelog handling. Changelog.php and ChangelogsController.php pass persisted, attacker-influenced changelog data to PHP unserialize() without disabling allowed classes. Current endpoints store only arrays and scalars, so no direct HTTP injection path is known; database-seeded objects demonstrated arbitrary file writes and code execution.
