{"id":"CVE-2026-48074","summary":"OpenReception: Staff deletion removes pending invites cross-tenant by email match","details":"OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.6, when a TENANT_ADMIN deletes an existing staff user, the underlying `StaffService.deleteStaffMember()` runs an additional invite cleanup that deletes from the central `user_invite` table by email. The `email` clause has no `tenantId` predicate. Any pending invite in any tenant that shares the deleted staff's email is removed. A TENANT_ADMIN of tenant A who deletes a staff record with email `victim[@]example[.]com` also deletes the pending invite for `victim[@]example[.]com` in tenant B, even though they have no relationship to tenant B. The user-side delete is correctly scoped (`eq(user.id, staffId), eq(user.tenantId, tenantId)`), and the pending-invite-only delete path (when `staffId` is itself an invite ID) is also tenant-scoped. The bug is specifically in the invite cleanup that runs as a side effect of deleting an existing staff user. Version 1.0.6 patches the issue.","aliases":["GHSA-6f8g-wfxp-mqxw"],"modified":"2026-08-12T03:51:48.598447569Z","published":"2026-08-06T20:27:21.240Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48074.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48074.json"},{"type":"ADVISORY","url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-6f8g-wfxp-mqxw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48074"},{"type":"FIX","url":"https://github.com/open-reception/appointment-booking-software/commit/5e77fd1df4262d09bfa6b59acfec4f66408de570"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-reception/appointment-booking-software","events":[{"introduced":"0"},{"fixed":"5e77fd1df4262d09bfa6b59acfec4f66408de570"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.0.6"}]}}],"versions":["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-2026-48074.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N"}]}
