GHSA-9h5v-pfqq-x599ModerateUAParser.js: Unbounded `Sec-CH-UA-Model` parsing can trigger ReDoS in `withClientHints()`### Summary A regular expression denial-of-service (ReDoS) vulnerability has been discovered in `ua-parser-js` 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 the parser to spend excessive CPU time due to catastrophic backtracking in the device [regex](https://github.com/faisalman/ua-parser-js/blob/2.0.9/src/main/ua-parser.js#L615): ```js / ([\w ]+) miui\/v?\d/i ``` Unlike when using the `User-Agent` value, which has a hard limit of `UA_MAX_LENGTH = 500`, when using Clien

GHSA-fhg7-m89q-25r3HighReDoS Vulnerability in ua-parser-js version### Description: A regular expression denial of service (ReDoS) vulnerability has been discovered in `ua-parser-js`. ### Impact: This vulnerability bypass the library's `MAX_LENGTH` input limit prevention. By crafting a very-very-long user-agent string with specific pattern, an attacker can turn the script to get stuck processing for a very long time which results in a denial of service (DoS) condition. ### Affected Versions: From version `0.7.30` to before versions `0.7.33` / `1.0.33`. ### Patches: A patch has been released to remove the vulnerable regular expression, update to version `0.

This link is maintained to preserve external references. ### Original Description A vulnerability was found in ua-parser-js 0.7.29/0.8.0/1.0.0. It has been rated as critical. This issue affects the crypto mining component which introduces a backdoor. Upgrading to version 0.7.30, 0.8.1 and 1.0.1 is able to address this issue. It is recommended to upgrade the affected component.
