Linux Distros Unpatched Vulnerability : CVE-2026-14180

medium Nessus Plugin ID 334575

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.

- A flaw was found in the ChunkReader component of the Undertow HTTP server, which is used by WildFly and JBoss EAP to handle chunked transfer encoding. The issue occurs because the parser uses a single internal variable to store both the remaining chunk size and state flags. By sending a specially crafted request with an extremely large chunk size, an attacker can cause these values to overlap, tricking the parser into thinking a request has finished prematurely. This can allow a second, smuggled request to be processed out of sync, potentially bypassing security controls. (CVE-2026-14180)

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

Solution

There is no known solution at this time.
