{"schema":"threatline.record/2","record":{"id":"CVE-2026-65825","aliases":["GHSA-v4q4-xmqf-gmq8"],"summary":"OpenReception: one tenant's throttle row disables the PIN brute-force throttle for the same identifier in other tenants","details":"OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. 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.","categories":["Unclassified"],"product":"appointment-booking-software","vendor":"open-reception","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-65825","source_modified_at":"2026-10-23T20:29:17.174Z","fetched_at":"2026-10-23T20:37:03.234832Z","product":"appointment-booking-software","vendor":"open-reception","versions":[{"version":"<= 2.1.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T20:29:17.174Z","modified_at":"2026-10-23T20:29:17.174Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-65825","fetched_at":"2026-10-23T20:37:03.234832Z","source_modified_at":"2026-10-23T20:29:17.174Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-v4q4-xmqf-gmq8","tags":["x_refsource_CONFIRM"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T20:29:17.174Z","content_hash":"14d3735387dac2337d8f087034c0b05421a0c1afff7cb3289a73a20ac61c419c"}}
