CVE-2026-38979: Ajenti clickjacking weakness in administrative UI

CVE-2026-38979 · Severity: info · CVSS 0 · Published 2026-07-06

Ajenti, a server administration panel, contains a security weakness that could allow an attacker to trick users into performing unintended actions. By embedding the Ajenti interface into a malicious website, an attacker could overlap invisible buttons or forms over the legitimate UI. This could lead to unauthorized configuration changes or administrative actions if a logged-in administrator is deceived into clicking on the page.

Technologies: Ajenti. Vendors: Ajenti.

Technical details

Ajenti through v2.2.13 is vulnerable to clickjacking due to the absence of defensive HTTP headers in its core response path. Specifically, in `ajenti-core/aj/http.py`, the application initializes an empty header list and finalizes responses via WSGI `start_response()` without enforcing `X-Frame-Options` or `Content-Security-Policy: frame-ancestors`. This allows the administrative UI to be rendered within an <iframe> on a remote, attacker-controlled domain. An attacker can exploit this to perform UI redressing attacks against authenticated users. A patch has been identified in the project's repository that explicitly adds these headers if they are not already present.
