{"id":"CVE-2026-48077","state":"PUBLISHED","title":"OpenReception: GET appointment by ID returns full appointment record without authorization","description":"OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. 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.","publishedAt":"2026-08-06T20:47:06.576Z","updatedAt":"2026-08-07T17:09:07.285Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["open-reception appointment-booking-software"],"affected":[{"vendor":"open-reception","product":"appointment-booking-software","versions":[{"version":"< 1.1.0","status":"affected"}]}],"references":["https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-8547-9x2c-9vmf","https://github.com/open-reception/appointment-booking-software/commit/16474d96c591e246a103b9d6aa15ca30d436d11b"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/48xxx/CVE-2026-48077.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-48077","state":"PUBLISHED","datePublished":"2026-08-06T20:47:06.576Z","dateUpdated":"2026-08-07T17:09:07.285Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-20T18:25:25.708Z"},"containers":{"cna":{"title":"OpenReception: GET appointment by ID returns full appointment record without authorization","descriptions":[{"lang":"en","value":"OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform.
