CVE-2026-111753: @angular/common: XSRF Token Leakage via URL Parsing Discrepancy in Angular HTTP Client (Incomplete fix for CVE-2025-66035)
An incomplete fix for GHSA-58c5-g7wp-6w37 (CVE-2025-66035) in @angular/common’s HTTP Client (HttpClient) allows Cross-Site Request Forgery (XSRF) tokens to be leaked to attacker-controlled cross-origin domains when requests use URLs that exploit parsing discrepancies between regular expressions and the browser’s WHATWG URL parser.
