CVE-2024-56197Network attack vector

Authenticated disclosure of private-message titles and metadata

Published Feb 4, 2025 · Updated Feb 5, 2025

Information disclosure in Discourse stable 3.3.3 and earlier allows remote authenticated users to read tagged private-message titles and metadata. Discourse has not published the code locus or operation that exposes this information; affected beta and tests-passed builds extend through 3.4.0.beta4. Exposure requires the PM-tags group option to include a group containing the user and the private message to carry a tag, and it is limited to titles and metadata.
