CVE-2022-39355 – Discourse Patreon vulnerable to improper validation of email during Patreon authentication

https://notcve.org/view.php?id=CVE-2022-39355

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. • https://github.com/discourse/discourse-patreon/commit/846d012151514b35ce42a1636c7d70f6dcee879e https://github.com/discourse/discourse-patreon/security/advisories/GHSA-fvj9-f67v-qpr4 • CWE-287: Improper Authentication •
