CVE-2023-31142

Discourse is an open source discussion platform. Prior to version 3.0.4 of the `stable` branch and version 3.1.0.beta5 o

Discourse is an open source discussion platform. Prior to version 3.0.4 of the stable branch and version 3.1.0.beta5 of the beta and tests-passed branches, if a site has modified their general category permissions, they could be set back to the default. This issue is patched in version 3.0.4 of the stable branch and version 3.1.0.beta5 of the beta and tests-passed branches.

A workaround, only if you are modifying the general category permissions, is to use a new category for the same purpose.
