Maddy Mail Server is an open source SMTP compatible email server. Versions of maddy prior to 0.5.4 do not implement password expiry or account expiry checking when authenticating using PAM. Users are advised to upgrade. Users unable to upgrade should manually remove expired accounts via existing filtering mechanisms.

GHSA-6cp7-g972-w9m9 — Use of a Key Past its Expiration Date and Insufficient Session Expiration in Maddy Mail Server

Affected: Go: github.com/foxcpp/maddy

### Impact

Any configuration on any maddy version <0.5.4 using auth.pam is affected.

No password expiry or account expiry checking is done when authenticating using PAM.

### Patches

Patch is available as part of the 0.5.4 release.

### Workarounds

If /etc/shadow authentication is used, it is possible to replace auth.pam with auth.shadow which is not affected.

It is possible to blacklist expired accounts via existing filtering mechanisms (e.g. auth_map to invalid accounts in storage.imapsql).
