Vulnerability AssessmentAI

Risk Assessment	The CVSS 5.3 score reflects a network-accessible vulnerability requiring low privileges (authenticated moderator account) with low confidentiality impact and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated Discourse moderator with standard report-viewing privileges navigates to an admin-restricted report (e.g., monthly user suspension analytics or abuse complaint summaries) and selects the CSV export option. Due to the missing authorization check, the export succeeds despite the report being flagged as admin-only, returning sensitive operational data that the moderator should not access. …
Remediation	Upgrade to Discourse 2026.1.3, 2026.2.2, or 2026.3.0 (or later) depending on your current version branch. … Detailed patch versions, workarounds, and compensating controls in full report.
