Prior to 1.8.221, FreeScout allows a non-admin user to permanently delete an internal note (private thread) from any conversation, even after that user's access to the mailbox containing the conversation has been revoked. The ThreadPolicy::delete authorization policy does not verify mailbox membership, so a former team member retains destructive write access to notes they created. This vulnerability is fixed in 1.8.221."}],"source":{"advisory":"GHSA-9vx8-gx3p-9mh6","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-9vx8-gx3p-9mh6","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-01T15:15:00.790272Z","id":"CVE-2026-48811","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-01T15:15:07.882Z"}}]}}
