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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4},"cwes":["CWE-294"],"references":["https://github.com/open-reception/appointment-booking-software/commit/da921eb9d36953276577c0a6deb9267bfec03622","https://github.com/open-reception/appointment-booking-software/releases/tag/v2.2.1","https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-hvcx-8476-rwv6"],"products":[],"source":"nvd","synced_at":"2026-10-26T14:12:07.966927945+00:00"},"epss":{"cve":"CVE-2026-65824","score":0.00252,"percentile":0.16551,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
