CVE-2021-47941Public exploitNetwork attack vector

Database disclosure via unauthenticated wp_sap SQL injection

Published May 10, 2026 · Updated May 10, 2026

SQL injection in Pantherius WordPress Survey & Poll 1.5.7.3 allows remote attackers to execute arbitrary SQL through a wp_sap cookie. The sss_params processing path accepts a JSON array from wp_sap and fails to neutralize a closing quote and appended UNION SELECT before database use. No authentication or user interaction is required; a request to a page containing a poll can disclose database names, tables, columns, and stored records.
