CVE-2026-79920

CRITICAL9.9

Published 2026-09-21 · Source security-advisories@github.com

Description

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.

CVE-2026-85751
Mailu is a mail server distributed as a set of Docker images. From Mailu 2.0 until 2024.06.55 and prior to Mailu helm-charts 2.7.3, deployments with PROXY_AUTH_WHITELIST configured but REAL_IP_HEADER unset trusted a client-controlled X-Forwarded-By header for header-based proxy authentication. The proxy_hide_header directive in the nginx template at core/nginx/conf/proxy.conf hid the header from upstream responses but did not overwrite the incoming request value in this configuration. An unauthenticated remote attacker could therefore spoof the trusted proxy identity and bypass authentication. This issue is fixed in Mailu 2024.06.55 and Mailu helm-charts 2.7.3.

The fix for CVE-2026-47065/ZDRES-232 ("resolveProxyClass Not Overridden - acceptMatchers Filter Bypass via java.lang.reflect.Proxy"), released on 2026-06-02 and announced as "Fully addressed" in MINA 2.2.8, 2.1.13 and 2.0.29, was committed to the 2.2.X branch only. The 2.0.X and 2.1.X maintenance branches never received the resolveProxyClass() override, so the 2.0.29 and 2.1.13 artifacts listed as fixed -- and every later release on those lines, up to and including the current 2.0.30 and 2.1.14 -- remain vulnerable to the exact allow-list bypass that CVE-2026-47065 was meant to close.
