Linux Distros Unpatched Vulnerability : CVE-2026-13006

high Nessus Plugin ID 323661

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including version 1.5.35 in Java applications, allows an attacker to execute arbitrary code circumventing existing protections against CVE-2025-11226 by compromising an existing logback configuration file or by injecting an environment variable before program execution. A successful attack requires the presence of Janino library to be present on the user's class path. In addition, the attacker must have write access to a configuration file. Alternatively, the attacker could inject a malicious environment variable pointing to a malicious configuration file. In both cases, the attack requires existing privilege. (CVE-2026-13006)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
