Name of the Vulnerable Software and Affected Versions Discourse versions prior to the latest commit

Description Discourse is a platform for community discussion. In affected versions, any private message that includes a group had its title and participating user exposed to users that do not have access to the private messages. However, access control for the private messages was not compromised as users were not able to view the posts in the leaked private message despite seeing it in their inbox. The problematic commit was reverted around 32 minutes after it was made.

Recommendations Upgrade to the latest commit if running Discourse against the tests-passed branch.
