Penpot: Server-side session not invalidated on logout; stale auth-token cookie remains valid for full profile access
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, logout clears the browser's auth-token cookie without revoking the corresponding server-side session. A previously captured session token remains usable after the victim logs out and can continue to make authenticated requests with the victim's authority until natural expiration. This issue is fixed in version 2.18.0.
