{"cve":"CVE-2026-1708","nvd":{"published":"2026-03-11T08:16:03.150","modified":"2026-06-17T10:16:22.240","status":"Deferred","description":"The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin plugin for WordPress is vulnerable to blind SQL Injection in all versions up to, and including, 1.6.9.27. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-89"],"references":["https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/class-appointment-model.php#L1340","https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/class-appointment-model.php#L1413","https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/lib/td-util/class-td-db-model.php#L1019","https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/lib/td-util/class-td-db-model.php#L1025","https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/trunk/includes/class-appointment-model.php#L1340"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-1708","score":0.00422,"percentile":0.36593,"date":"2026-10-31"},"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).
