SCA: security update for @angular/compiler, @angular/core (GHSA-hh8m-fm6v-7cvg)

medium Tenable Self-Hosted Container Security Plugin ID 447952

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 20.3.28, 21.2.20, and 22.1.0, Angular's compiler and
 runtime in @angular/core and @angular/compiler could omit or select an incorrect sanitizer for security-
 sensitive directive host bindings because SecurityContext was derived from the declaring directive or
 component selector rather than the concrete host element. The mismatch is reachable through hostDirectives
 composition, inherited HostBinding declarations, createComponent with a custom hostElement or dynamic
 directives, SVG/MathML namespace elements, and tag-neutral selectors such as :not(...). Attacker-
 controlled href, src, action, xlink:href, or data values can therefore reach DOM attributes without
 Angular's built-in sanitizer and execute arbitrary JavaScript in the user's browser context. Applications
 unable to upgrade can use DomSanitizer.sanitize with SecurityContext.URL before assignment or restrict
 inputs to validated HTTP and HTTPS URL schemes. This issue is fixed in versions 20.3.28, 21.2.20, and
 22.1.0. (CVE-2026-88057)

Solution

Update the @angular/compiler library and its related packages to version 20.3.28 or later.
