SCA: security update for @angular/compiler, @angular/core (GHSA-f3m7-gqxr-g87x)

medium Tenable Self-Hosted Container Security Plugin ID 443199

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Angular is a development platform for building mobile and desktop web applications using
 TypeScript/JavaScript and other languages. Prior to 22.0.0-rc.2, 21.2.15, 20.3.22 and 19.2.22, an issue in
 the @angular/compiler and @angular/core packages allows bypassing element and attribute
 sanitization/validation through specific namespace workarounds. Specifically, namespaced script elements
 (e.g., <svg:script> or <:svg:script>) were not properly identified as script elements by the Angular
 template preparser, allowing them to pass through template compilation without being stripped.
 Furthermore, security context schema mappings for element attributes did not consistently handle
 attributes within namespaced elements (like SVG and MathML), opening up gaps where malicious namespaced
 attributes could bypass runtime and compile-time sanitizers. Combined, these flaws enable an attacker who
 can inject or supply a template/tag structure with custom namespaces to bypass Angular's script-stripping
 logic and attribute sanitizers, leading to client-side Cross-Site Scripting (XSS). This vulnerability is
 fixed in 22.0.0-rc.2, 21.2.15, 20.3.22 and 19.2.22. (CVE-2026-50557)

Solution

Update the @angular/compiler library and its related packages to version 19.2.22 or later.
