Technical description

Discourse Patreon enables syncronization between Discourse Groups and Patreon rewards. On sites with Patreon login enabled, an improper authentication vulnerability could be used to take control of a victim's forum account. This vulnerability is patched in commit number 846d012151514b35ce42a1636c7d70f6dcee879e of the discourse-patreon plugin. Out of an abundance of caution, any Discourse accounts which have logged in with an unverified-email Patreon account will be logged out and asked to verify their email address on their next login. As a workaround, disable the patreon integration and log out all users with associated Patreon accounts.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
