Name of the Vulnerable Software and Affected Versions Discourse versions prior to 2026.3.0-latest.1 Discourse versions prior to 2026.2.1 Discourse versions prior to 2026.1.2

Description Discourse is an open-source discussion platform. The Post Edits admin report, accessible via the ''/admin/reports/post edits'' API endpoint, improperly exposed the initial 40 characters of raw post content from private messages and secure categories to moderators lacking the necessary permissions. This information leak affected content that should have remained confidential.

Recommendations Update to Discourse version 2026.3.0-latest.1 or later. Update to Discourse version 2026.2.1 or later. Update to Discourse version 2026.1.2 or later.
