CVE-2026-56130Network attack vector

Authentication bypass via expired persistent-cookie replay

Published Jun 25, 2026 · Updated Jun 25, 2026

Authentication bypass in Apache Shiro 1.2.4 through 2.x and 3.0.0-alpha-1 allows remote attackers to replay expired persistent-login cookies. CookieRememberMeManager restores principals from a decrypted persistent-login cookie without checking a server-verifiable issuance time or maximum age, leaving client expiry as the lifetime control. Persistent-login functionality must be enabled, and exploitation requires an intercepted valid cookie; replay restores the captured identity after configured expiry.
