CVE-2024-25128Network attack vector

Unauthorized access via unvalidated OpenID provider

Published Feb 28, 2024 · Updated Aug 26, 2024

Improper authentication in Flask-AppBuilder before 4.3.11 allows remote attackers to gain unauthorized privileges through OpenID 2.0. AuthOIDView.login_handler passes the submitted provider value directly to oid.try_login instead of resolving it against OPENID_PROVIDERS. Exploitation requires AUTH_TYPE AUTH_OID and a backend-reachable attacker-controlled OpenID service; successful authentication grants unauthorized application access.
