Prior to version 1.1.0, the GET handler at `/api/tenants/{id}/appointments/{appointmentId}` performs no authorization check before returning the appointment record. Any party who knows or obtains a valid appointment UUID receives the full row, including channel and agent IDs, time and timezone, status, and the AES-GCM ciphertext components (`encryptedPayload`, `iv`, `authTag`, `dataKey`). The same file's DELETE handler calls `checkPermission(locals, tenantId, true)` before allowing deletion. The intent is clear: appointment records are tenant-scoped and require authentication to access. The GET handler is missing the equivalent call. The middleware chain (`apiAuthHandle`, `authGuard`) does not compensate: API paths bypass `authGuard` entirely, and `apiAuthHandle` does not block requests to non-admin paths when no token is present. Version 1.1.0 patches the issue."}],"source":{"advisory":"GHSA-8547-9x2c-9vmf","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-8547-9x2c-9vmf","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-07T15:00:28.462761Z","id":"CVE-2026-48077","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"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":"2026-08-07T17:09:07.285Z"}}]}}
