CVE-2025-66035 describes a Cross-Site Request Forgery (XSRF) token leakage vulnerability in Angular versions prior to 19.2.16, 20.3.14, and 21.0.1. This flaw allows an attacker to obtain the XSRF token due to Angular's HttpClient incorrectly treating protocol-relative URLs (e.g., //example.com) as same-origin, leading to the token being sent to attacker-controlled domains. The vulnerability has a CVSSv4 score of 7.7 (High), indicating a network-based attack with low complexity and a high impact on confidentiality, as it enables unauthorized disclosure of sensitive credentials. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
