MEDIUM 6.5

DescriptionCVE.org

The SQL Chart Builder WordPress plugin before 2.3.8 does not properly escape user input as it is concatened to SQL queries, making it possible for attackers to conduct SQL Injection attacks against the dynamic filter functionality.

AnalysisAI

SQL injection in SQL Chart Builder WordPress plugin before version 2.3.8 allows remote attackers to execute arbitrary SQL queries through the dynamic filter functionality due to improper input escaping. The vulnerability affects all versions before 2.3.8, requires no authentication or user interaction, and carries a moderate CVSS score of 6.5 with low real-world exploitation probability (EPSS 0.02%). Publicly available exploit code exists, though the low EPSS percentile suggests limited active exploitation relative to the attack surface.

Technical ContextAI

SQL Chart Builder is a WordPress plugin that constructs SQL queries dynamically based on user-supplied filter parameters. The plugin concatenates user input directly into SQL query strings without proper sanitization or parameterized query preparation, violating secure coding practices for database interactions. This is a classic SQL injection vulnerability (CWE category related to improper input validation) affecting the dynamic filter feature. The vulnerability arises from the plugin's failure to use prepared statements or escape special SQL characters in user inputs before concatenation, allowing attackers to break out of intended query context and inject arbitrary SQL commands.

RemediationAI

Vendor-released patch: Update SQL Chart Builder to version 2.3.8 or later, which properly escapes user input before SQL query concatenation. Site administrators using this plugin should immediately upgrade through the WordPress plugin management interface or by downloading the latest version directly from the plugin repository. No interim workarounds are documented; upgrading is the primary remediation path. Organizations unable to immediately patch should consider disabling the plugin's dynamic filter functionality if possible, though this may limit feature availability. Consult the WPScan advisory and NVD entry for confirmation of patch completeness.
