A session invalidation flaw exists in x-ui 0.3.2. The full user object is stored in a client-side signed cookie, and authentication only checks that a user object can be retrieved from the cookie without re-validating against the database or any session version. When an administrator changes the username or password, previously issued session cookies are not revoked, so an attacker who holds a pre-change admin cookie can continue accessing and operating the management interface after the credentials have been rotated.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
