Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in RealMag777 TableOn posts-table-filterable allows Blind SQL Injection.This issue affects TableOn: from n/a through <= 1.0.5.1.

AnalysisAI

Unauthenticated blind SQL injection in the RealMag777 TableOn (posts-table-filterable) WordPress plugin through version 1.0.5.1 lets remote attackers inject crafted SQL into backend queries without credentials or user interaction. Because the CVSS scope is marked changed (S:C) with high confidentiality impact, a successful attack can read data beyond the vulnerable component, including the WordPress database. No public exploit is identified at time of analysis, and the EPSS score is very low (0.03%, 9th percentile), indicating no current sign of widespread exploitation despite the 9.3 base score.
