{"id":"CVE-2026-48077","summary":"OpenReception: GET appointment by ID returns full appointment record without authorization","details":"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.","aliases":["GHSA-8547-9x2c-9vmf"],"modified":"2026-08-09T03:30:40.149955054Z","published":"2026-08-06T20:47:06.576Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48077.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48077.json"},{"type":"ADVISORY","url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-8547-9x2c-9vmf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48077"},{"type":"FIX","url":"https://github.com/open-reception/appointment-booking-software/commit/16474d96c591e246a103b9d6aa15ca30d436d11b"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-reception/appointment-booking-software","events":[{"introduced":"0"},{"fixed":"16474d96c591e246a103b9d6aa15ca30d436d11b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.1.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.2","v1.0.1","v1.0.0","v1.0.0-rc2","v1.0.0-rc"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48077.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
