Detailsinfo

A vulnerability was found in Ajenti up to 2.2.15 and classified as very critical. This issue affects an unknown part of the file plugins/plugins/tasks.py of the component Plugin Management. The manipulation of the argument name/version with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Ajenti is a Linux & BSD modular server admin panel. Prior to version 2.2.16, any authenticated user can call /api/core/tasks/start to enqueue InstallPlugin, UnInstallPlugin, or UpgradeAll from plugins/plugins/tasks.py without plugin-management authorization. InstallPlugin and UnInstallPlugin construct a pip package specification from unvalidated name and version fields, and the task worker invokes pip while running as root. A low-privileged user can therefore select or manipulate a package installed with root privileges and can install, remove, or upgrade plugins without administrative permission, resulting in root code execution and full host compromise. This issue is fixed in version 2.2.16.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-79920 since 08/25/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/21/2026). MITRE ATT&CK project uses the attack technique T1068 for this issue.
