https://notcve.org/view.php?id=CVE-2023-34250
Discourse is an open source discussion platform.

https://notcve.org/view.php?id=CVE-2023-32061
Discourse is an open source discussion platform. Prior to version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches, the lack of restrictions on the iFrame tag makes it easy for an attacker to exploit the vulnerability and hide subsequent comments from other users. This issue is patched in version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches. There are no known workarounds. • https://github.com/discourse/discourse/security/advisories/GHSA-prx4-49m8-874g • CWE-863: Incorrect Authorization •
CVSS: 5.3EPSS: 0%CPEs: 5EXPL: 0CVE-2023-31142 – Discourse's general category permissions could be set back to default
https://notcve.org/view.php?id=CVE-2023-31142
Discourse is an open source discussion platform. Prior to version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches, if a site has modified their general category permissions, they could be set back to the default. This issue is patched in version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches. A workaround, only if you are modifying the general category permissions, is to use a new category for the same purpose. • https://github.com/discourse/discourse/security/advisories/GHSA-286w-97m2-78x2 • CWE-732: Incorrect Permission Assignment for Critical Resource •
