{"id":"CVE-2026-65824","summary":"OpenReception: invite confirmation token is replayable within its validity window and re-issues a registration-bootstrap cookie","details":"OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 2.2.1, an attacker who captures a pending invite token can replay it to obtain a passkey-registration credential and register their own passkey on the invited account, taking control of that account. For a staff or tenant-admin invite this yields access to the tenant context tied to that account. This issue has been patched in version 2.2.1.","aliases":["GHSA-hvcx-8476-rwv6"],"modified":"2026-11-01T02:30:47.706946958Z","published":"2026-10-23T20:27:52.852Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65824.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-294"]},"references":[{"type":"WEB","url":"https://github.com/open-reception/appointment-booking-software/releases/tag/v2.2.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65824.json"},{"type":"ADVISORY","url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-hvcx-8476-rwv6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65824"},{"type":"FIX","url":"https://github.com/open-reception/appointment-booking-software/commit/da921eb9d36953276577c0a6deb9267bfec03622"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-reception/appointment-booking-software","events":[{"introduced":"0"},{"fixed":"fffc45a1d6ccc11bf94e493674def8d8fdc732d4"},{"fixed":"da921eb9d36953276577c0a6deb9267bfec03622"}],"database_specific":{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"2.2.1"}],"source":"AFFECTED_FIELD"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"da921eb9d36953276577c0a6deb9267bfec03622"}]},{"range":[{"fixed":"fffc45a1d6ccc11bf94e493674def8d8fdc732d4"}],"source":"REFERENCES_TAG","original_tag":"v2.2.1"}]}}],"versions":["v2.2.0","v2.1.0","v2.0.1","v2.0.0","v1.1.1","v1.1.0","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-2026-65824.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
