The vulnerability exists in all Discourse releases prior to these patched versions. No known workarounds are available; the only mitigation is to apply the patch or upgrade to a newer release.", "description_and_impact": "The vulnerability in Discourse allows a moderator to perform a privilege escalation by supplying an arbitrary post_id to the suspend/silence endpoint. Key issue is that the endpoint does not properly authorize access to post objects outside the moderator's scope. As a result, moderators are able to edit site policy documents such as the Terms of Service, community guidelines, and privacy policy, which they are explicitly prohibited from modifying. This creates an integrity violation that can undermine trust in the platform and lead to policy misinformation. CWE-269 describes this as an access control flaw.", "risk_and_exploitability": "The CVSS score is 2.2, indicating low severity. EPSS data is not available, and the vulnerability has not been listed in the CISA KEV catalog. The attack requires legitimate moderator access, so the vector is internal or trusted. An attacker with moderator credentials can easily exploit the flaw by directly calling the suspend/silence endpoint with a crafted post_id. The exploit is straightforward and does not require external network exposure, but it does not affect unprivileged users."}}}}, "created": "2026-03-20T08:52:56.953253+00:00", "updated": "2026-03-20T10:37:40.234951+00:00", "vendors": ["discourse", "discourse$PRODUCT$discourse"]}
