CVE-2026-7797Network attack vector

Unauthenticated database disclosure via blind SQL injection

Published May 28, 2026 · Updated May 28, 2026

Time-based blind SQL injection in Simply Schedule Appointments 1.6.11.8 and earlier allows remote attackers to read WordPress database data. The /appointments/bulk REST path passes append_where_sql into an insufficiently prepared query after a form-encoded PUT evades the PHP-superglobal blocklist. A public nonce embedded in the booking widget exposes the route without an account; successful requests disclose data through timing differences without granting database writes.
