CVE-2023-22739: Discourse

Medium severity, CVSS 6.5. EPSS: 0.9% chance of exploitation in the next 30 days.

Discourse is an open source platform for community discussion. Versions prior to 3.0.1 (stable), 3.1.0.beta2 (beta), and 3.1.0.beta2 (tests-passed) are subject to Allocation of Resources Without Limits or Throttling. As there is no limit on data contained in a draft, a malicious user can create an arbitrarily large draft, forcing the instance to a crawl. This issue is patched in versions 3.0.1 (stable), 3.1.0.beta2 (beta), and 3.1.0.beta2 (tests-passed). There are no workarounds.

Affected products

• Discourse Discourse: before 3.0.1 (fixed in 3.0.1); version 3.1.0 only
