CVE-2024-21490 — HIGH (7.5)

Vulnerability Description

This affects versions of the package angular from 1.3.0. A regular expression used to split the value of the ng-srcset directive is vulnerable to super-linear runtime due to backtracking. With large carefully-crafted input, this can result in catastrophic backtracking and cause a denial of service. **Note:** This package is EOL and will not receive any updates to address this issue. Users should migrate to [@angular/core](https://www.npmjs.com/package/@angular/core).
