This is due to the `db_where_conditions` method in the `TD_DB_Model` class failing to prevent the `append_where_sql` parameter from being passed through JSON request bodies, while only checking for its presence in the `$_REQUEST` superglobal. This makes it possible for unauthenticated attackers to append arbitrary SQL commands to queries and extract sensitive information from the database via the `append_where_sql` parameter in JSON payloads granted they have obtained a valid `public_token` that is inadvertently exposed during the booking flow."}],"title":"Appointment Booking Calendar <= 1.6.9.27 - Unauthenticated SQL Injection via 'append_where_sql' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/71642341-9fe0-44a9-88f3-70167dc6ca62?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/trunk/includes/lib/td-util/class-td-db-model.php#L1019"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/lib/td-util/class-td-db-model.php#L1019"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/trunk/includes/lib/td-util/class-td-db-model.php#L1025"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/lib/td-util/class-td-db-model.php#L1025"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/trunk/includes/class-appointment-model.php#L1340"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/class-appointment-model.php#L1340"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/trunk/includes/class-appointment-model.php#L1413"},{"url":"https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/class-appointment-model.php#L1413"},{"url":"https://plugins.trac.wordpress.org/changeset/3475885/simply-schedule-appointments/trunk/includes/lib/td-util/class-td-db-model.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')","cweId":"CWE-89","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Thanh Hao"}],"timeline":[{"time":"2026-01-30T16:42:44.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-03-10T19:14:37.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-11T13:50:25.957126Z","id":"CVE-2026-1708","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-11T13:50:40.662Z"}}]}}
