Linux Distros Unpatched Vulnerability : CVE-2026-48125

medium Nessus Plugin ID 327207

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.

- UAParser.js is a JavaScript library to detect browsers, operating systems, CPUs, and devices from user- agent data. From 2.0.1 until 2.0.10, a regular expression denial-of-service vulnerability exists when using the Client Hints API. By sending a crafted Sec-CH-UA-Model header to an application that calls UAParser(headers).withClientHints(), an attacker can cause excessive CPU time due to catastrophic backtracking in the device regex because Client Hints values are copied without the UA_MAX_LENGTH limit used for User-Agent values. This issue is fixed in version 2.0.10. (CVE-2026-48125)

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

Solution

There is no known solution at this time.
