Nagios · Nagios · CVE-2026-24892
**Name of the Vulnerable Software and Affected Versions**
openITCOCKPIT Community Edition versions prior to 5.3.1
**Description**
openITCOCKPIT is a monitoring tool compatible with Nagios, Naemon, and Prometheus. The software contains an unsafe PHP deserialization pattern when handling changelog entries. Specifically, serialized changelog data originating from attacker-controlled application state is deserialized without class restrictions. While no current application endpoint directly introduces PHP objects into this data path, the unrestricted use of `unserialize()` creates a potential PHP object injection issue. Future modifications, plugins, or refactoring that introduce object values into this path could lead to immediate exploitability, potentially resulting in remote code execution.
**Recommendations**
Update to a version newer than 5.3.1.
