CVE-2023-32061 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
