What is CVE-2026-79317?
CVE-2026-79317 is a medium-severity authentication bypass vulnerability in n/a, published on 21 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-613
