CVE-2026-42755Network attack vector

Unauthenticated blind database data disclosure

Published May 27, 2026 · Updated May 27, 2026

Blind SQL injection in RealMag777 TABLEON through 1.0.5.1 allows remote attackers to disclose database data without authentication. Patchstack and the CNA record do not identify the affected parameter, request route, function, or query-construction error beyond improper neutralization of SQL syntax. Exploitation requires network access to a WordPress site running the plugin, with no privileges or user interaction; published impacts are disclosure and limited service interruption, not data modification.
