"Remember me" cookie age is not verified on the server. This potentially allows an attacker to intercept a valid cookie and reuse it indefinitely, even after the configured expiration time has passed. This issue affects all Apache Shiro versions from 1.2.4 through 2.x, and 3.0.0-alpha-1, only when RememberMe functionality is enabled.

Upgrade to version 3.0.0 or later, which fixes the issue.
