Discourse is an open source platform for community discussion. Tags that are normally private are showing in metadata. This affects any site running the `tests-passed` or `beta` branches >= 3.1.0.beta2. The issue is patched in the latest `beta` and `tests-passed` version of Discourse.
CVSS 5.3
CVE-2023-28107 WRITEUP MEDIUM WRITEUP
Discourse < 3.0.1 - Resource Allocation Without Limits
Discourse is an open-source discussion platform. Prior to version 3.0.2 of the `stable` branch and version 3.1.0.beta3 of the `beta` and `tests-passed` branches, a user logged as an administrator can request backups multiple times, which will eat up all the connections to the DB. If this is done on a site using multisite, then it can affect the whole cluster. The vulnerability is patched in version 3.0.2 of the `stable` branch and version 3.1.0.beta3 of the `beta` and `tests-passed` branches. There are no known workarounds.
CVSS 4.5
CVE-2025-32376 WRITEUP MEDIUM WRITEUP
Discourse < 3.4.3 - Improper Access Control
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.
