CVE-2025-69202Public exploitNetwork attack vector

Cross-session data disclosure via ignored Vary header

Published Dec 29, 2025 · Updated Dec 29, 2025

Authorization bypass in Axios Cache Interceptor before 1.11.1 allows remote authenticated users to read other users' cached data. The default cache-key generator keys requests by URL and disregards response Vary directives, so Authorization values do not partition cached responses. Exploitation requires a server-side application that reuses one cached Axios instance across authenticated users and calls an upstream service that returns Vary: Authorization; browser-only single-user sessions are not affected.
