CVE-2023-42446

Summary

CVE-2023-42446 is a vulnerability affecting Pow, an authentication and user management solution for Phoenix and Plug-based apps. In versions prior to 1.0.34, the use of `Pow.Store.Backend.MnesiaCache` leads to session hijacking due to incorrect handling of expired keys during startup. When all `Pow.Store.Backend.MnesiaCache` instances have been shut down for a duration longer than a session's Time to Live (TTL), the session may expire. Version 1.0.34 includes a patch for this issue, and as a temporary measure, expired keys, including sessions, can be manually invalidated.
