Discourse DM limits aren’t always properly enforced (CVE-2025-32376)

Summary

Discourse DM limits aren’t always properly enforced

Original description

The description as published by the source.

Discourse is an open-source discussion platform. Prior to versions 3.4.3 on the stable branch and 3.5.0.beta3 on the beta branch, the users limit for a DM can be bypassed, thus giving the ability to potentially create a DM with every user from a site in it. This issue has been patched in stable version 3.4.3 and beta version 3.5.0.beta3.
