Vulnerability in Olivetin
CVE-2026-30224
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, OliveTin does not revoke server-side sessions when a user logs out. Although the browser cookie is cleared, the corresponding session remains valid in server storage until expiry (default ≈ 1 year). An attacker with a previously stolen or captured session cookie can continue authenticating after logout, resulting in a post-logout authentication bypass. This is a session management flaw that violates expected logout semantics. This issue has been patched in version 3000.11.1.
