In versions 2.1.0 and prior, a returning client's six-digit booking PIN can be brute-forced online in the victim tenant. A successful guess yields the client's booking access token, granting access to that client's appointment tunnel, which holds their end-to-end-encrypted appointment data, and the ability to act as the client, for example adding or cancelling appointments in the tunnel. The bypass is cross-tenant: state owned by one tenant removes an authentication protection of a different tenant. This crossing of the tenant boundary is the basis for the scope-changed vector. At time of publication, there are no publicly available patches.","state":0,"publishedAt":"2026-10-23T20:29:17.174+00:00","modifiedAt":"2026-10-26T17:45:38.981+00:00","affected":[{"ecosystem":"Vendor product","name":"appointment-booking-software","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"open-reception\",\n                    \"product\": \"appointment-booking-software\",\n                    \"versions\": [\n                        {\n                            \"version\": \"<= 2.1.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-v4q4-xmqf-gmq8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-65825","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-65825","identifiers":["CVE-2026-65825"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
