SCA: security update for @angular/platform-server (GHSA-f67j-2jqw-jpq7)

high Tenable Self-Hosted Container Security Plugin ID 448443

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 20.3.31, 21.2.23, and 22.1.6, the @angular/platform-
 server DOM emulation parser can enter an infinite synchronous loop when Angular server-side rendering
 processes attacker-controlled HTML containing an incomplete DOCTYPE that ends with whitespace at end of
 input. In Domino lib/HTMLParser.js, after_doctype_name_state emits doctype and EOF tokens without
 advancing nextchar or leaving the fixed-lookahead state, so the scanner repeatedly handles the same EOF
 marker. A remote unauthenticated attacker can use this condition through server-side HTML parsing paths
 such as innerHTML binding to consume a Node.js SSR worker at full CPU, starve the event loop, and stop
 concurrent and subsequent requests. This issue is fixed in versions 20.3.31, 21.2.23, and 22.1.6.
 (CVE-2026-101895)

Solution

Update the @angular/platform-server library and its related packages to version 20.3.31 or later.
