CVE-2023-32061: Discourse

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Discourse Discourse: before 3.0.4 (fixed in 3.0.4); version 3.1.0 only
