CVE-2025-59786Network attack vector

Session persistence via incomplete token invalidation

Published Mar 4, 2026 · Updated Mar 4, 2026

Insufficient session expiration in 2N Access Commander 3.4.2 and earlier allows attackers to retain web access after logout. The web application's logout flow fails to invalidate all active session tokens, so previously issued session cookies remain usable. Possession of an existing session cookie and a user logout or password change are required; the retained cookie preserves account access.
