CVE-2025-32068Network attack vector

Persistent profile access via unrevoked refresh tokens

Published Apr 11, 2025 · Updated Jul 7, 2025

Incorrect authorization in Wikimedia Foundation OAuth 1.39 through 1.43 allows remote authenticated users to retain profile access. The refresh-token validation path checks cache revocation state but fails to verify that the backing access-token database row still exists after grant revocation. A previously authorized, non-owner-only OAuth2 consumer with a retained refresh token can mint replacement tokens and keep reading the user's profile or private email after consent is withdrawn.
