Angular < 20.3.28 Cross-Site Scripting

medium Web App Scanning Plugin ID 115588

Synopsis

Angular < 20.3.28 Cross-Site Scripting

Description

According to its self-reported version number, Angular is prior to 20.0.0, 20.x prior to 20.3.28, 21.x prior to 21.2.20 or 22.x prior to 22.1.0. It is, therefore, affected by a sanitization bypass vulnerability in @angular/core and @angular/compiler. The security context of directive host bindings is determined from the declaring directive selector rather than the concrete host element, allowing untrusted values (such as javascript: URLs) bound through host bindings to reach security-sensitive DOM attributes without sanitization, leading to Cross-Site Scripting (XSS). (CVE-2026-88057)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Angular version 20.3.28 or later.
