https://notcve.org/view.php?id=CVE-2022-39356

CVSS: 5.3EPSS: 0%CPEs: 10EXPL: 0CVE-2022-39378 – Displaying user badges can leak topic titles to users that have no access to the topic
https://notcve.org/view.php?id=CVE-2022-39378
Discourse is a platform for community discussion. Under certain conditions, a user badge may have been awarded based on a user's activity in a topic with restricted access. Before this vulnerability was disclosed, the topic title of the topic associated with the user badge may be viewed by any user. If there are sensitive information in the topic title, it will therefore have been exposed. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. • https://github.com/discourse/discourse/security/advisories/GHSA-2gvq-27h6-4h5f • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2022-39241
Discourse is a platform for community discussion. A malicious admin could use this vulnerability to perform port enumeration on the local host or other hosts on the internal network, as well as against hosts on the Internet. Latest `stable`, `beta`, and `test-passed` versions are now patched.
