node-ua-parser-js: UAParser.js is a JavaScript library to detect browsers, operating systems, CPUs, and devices from user-agent data
CVE-2026-48125 is fixed in node-ua-parser-js on 1 platform by DEBIAN-CVE-2026-48125 (version 2.0.10+ds+~cs0.3.5-1), released July 14, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
