Unauthenticated SQL injection via reverse DNS spoofing
Published Nov 26, 2024 · Updated Apr 8, 2026
SQL injection in Security & Malware scan by CleanTalk 2.145 and earlier allows remote attackers to read database data without authentication. The checkWithoutToken function trusts spoofable reverse-DNS results for authorization and appends insufficiently sanitized input to existing SQL queries. No account or user interaction is required; exploitation exposes sensitive WordPress database information without altering or interrupting the service.
