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. Users are encouraged to upgrade to the latest commit if they are running Discourse against the `tests-passed` branch.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
