CVE-2026-116251: pgAdmin 4 session invalidation failure after password change

CVE-2026-116251 · Severity: medium · CVSS 4.2 · Published 2026-10-30

pgAdmin 4 is a web-based management tool for PostgreSQL databases. When a user changes their password through the settings dialog or an administrator resets it, the application failed to log out the user's other active sessions. This means someone with an old password or a stolen session cookie could continue accessing the application and databases even after the password was changed, defeating the security action intended to revoke unauthorized access.

Technologies: Pgadmin 4. Vendors: pgAdmin.

Technical details

The vulnerability is a session persistence flaw in the authentication mechanism: pgAdmin 4 did not invalidate existing session identifiers (fs_uniquifier) when a password was changed. An attacker with a valid session cookie or knowledge of the old password could maintain access across multiple devices or sessions. The fix rotates the session identifier on password change, forcing re-authentication for all other sessions while preserving database connections for the session performing the change.
