CVE-2023-42446 is a vulnerability affecting the Pow authentication and user management solution for Phoenix and Plug-based apps. Versions 1.0.14 to 1.0.34 are susceptible to session hijacking as expired keys are not being invalidated correctly on startup. This can lead to a session being hijacked if all Pow.Store.Backend.MnesiaCache instances have been shut down for longer than the session's remaining time-to-live (TTL). The issue has been patched in version 1.0.34, but as a workaround, expired keys and sessions can be manually invalidated. This vulnerability poses a medium risk with a base severity score of 6.5, with low privileges required and no user interaction needed for exploitation. The potential impact is high in terms of integrity, but no confidentiality impact is expected.
