CVE-2024-25128 | Flask-AppBuilder incorrect authentication when using auth type OpenID

Flask-AppBuilder is an application development framework, built on top of Flask. When Flask-AppBuilder is set to AUTH_TYPE AUTH_OID, it allows an attacker to forge an HTTP request, that could deceive the backend into using any requested OpenID service. This vulnerability could grant an attacker unauthorised privilege access if a custom OpenID service is deployed by the attacker and accessible by the backend. This vulnerability is only exploitable when the application is using the OpenID 2.0 authorization protocol. Upgrade to Flask-AppBuilder 4.3.11 to fix the vulnerability.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
