Summary
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages.
Prior to 20.3.27, 21.2.19, and 22.0.1, the Angular compiler i18n pipeline permits i18n-onerror and other i18n-on event-handler attributes, allowing a lower-trust translation file to replace a static handler with executable JavaScript. This issue is fixed in versions 20.3.27, 21.2.19, and 22.0.1.
A remote attacker could exploit this by injecting malicious scripts, leading to Cross-Site Scripting (XSS). This could result in unauthorized access to sensitive information or actions performed on behalf of the user.
