listmonk is a standalone, self-hosted, newsletter and mailing list manager. From version 4.1.0 to before version 6.1.0, bugs in list permission checks allows users in a multi-user environment to access to lists (which they dont have access to) under different scenarios. This only affects multi-user environments with untrusted users. This issue has been patched in version 6.1.0.
