What is CVE-2025-24896?

The Misskey platform has a vulnerability where the login token, named 'token', remains stored in a cookie even after user logout. This flaw primarily affects users who access Misskey on public or shared devices, as it may expose their authentication credentials to subsequent users of the device. Even those who log out before lending their devices can be at risk if the token is not properly cleared. The issue is resolved in version 2025.2.0-alpha.0, which ensures that tokens are securely managed and deleted upon logout, enhancing user privacy and security.
