What is CVE-2025-46336?

Rack::Session, which provides session management for Rack applications, contains a vulnerability that allows an attacker to maintain access to a user session after the user has logged out. If the attacker secures a session cookie and triggers a long-running request during the logout process, they may restore the session, thus retaining illicit access. This situation represents a significant security risk, as it undermines user logout attempts and can lead to unauthorized actions under a user's account. This issue has been addressed and patched in Rack::Session version 2.1.1.
