SCA: security update for @angular/ssr (GHSA-69xr-m8h6-h664)

medium Tenable Cloud Security Plugin ID 441375

Description

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

- The Angular SSR is a server-rise rendering tool for Angular applications. From 19.0.0-next.0 to before
19.2.25, 20.3.25, 21.2.9, and 22.0.0-next.7, a vulnerability exists in the X-Forwarded-Prefix header
processing logic within Angular SSR. The internal validation mechanism fails to properly account for URL-
encoded characters, specifically dots (%2e%2e). This allows an attacker to bypass security filters by
injecting encoded path traversal sequences that are later decoded and utilized by the application logic.
When an Angular SSR application is configured to trust proxy headers and is deployed behind a proxy that
forwards the X-Forwarded-Prefix header without prior sanitization, an attacker can provide a payload such
as /%2e%2e/evil. This vulnerability is fixed in19.2.25, 20.3.25, 21.2.9, and 22.0.0-next.7.
(CVE-2026-44437)
