GHSA-jfgx-762w-99vr: @angular/common (CVE-2026-111753)

Package	Ecosystem	Affected	Fixed in
@angular/common	npm	>=21.0.0, <21.0.3 \|\| >=20.0.0, <20.3.34 \|\| <=19.2.25	21.0.3, 20.3.34

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Angular's @angular/common package is vulnerable in versions up to 19.2.25, from 20.0.0 before 20.3.34, and from 21.0.0 before 21.0.3, as an incomplete fix for CVE-2025-66035. A remote attacker who can make the application send a state-changing HTTP request to an attacker-chosen URL that exploits URL parsing differences can cause the XSRF token to be attached and sent to a cross-origin host, enabling cross-site request forgery against the victim's session. Upgrade to 20.3.34 or 21.0.3 (or any 22.x release), and until then avoid passing untrusted URLs to HttpClient mutating methods.
