    Regular Expression Denial of Service (ReDoS)

    ua-parser-js is a lightweight JavaScript-based user-agent string parser.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the withClientHints() function. An attacker can cause excessive CPU consumption by sending a specially crafted Sec-CH-UA-Model header containing a very large input, leading to significant processing delays due to inefficient regular expression handling.

    How to fix Regular Expression Denial of Service (ReDoS)?

    Upgrade ua-parser-js to version 2.0.10 or higher.
