Flask App Builder has an Authentication Bypass vulnerability when using non AUTH_DB methods

CVE-2025-58065 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

When Flask-AppBuilder is configured to use OAuth, LDAP, or other non-database authentication methods, the password reset endpoint remains registered and accessible, despite not being displayed in the user interface. This allows an enabled user to reset their password and be able to create JWT tokens even after the user is disabled on the authentication provider.

Patches

Upgrade to Flask-AppBuilder version 4.8.1 or later

Workarounds

If immediate upgrade is not possible:
- Manually disable password reset routes in the application configuration
- Implement additional access controls at the web server or proxy level to block access to the reset my password URL.
- Monitor for suspicious password reset attempts from disabled accounts

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
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:L)
A normal user session is enough; they don’t have to be admin.
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:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
