CVE-2026-5721 - Changeset Plugin
CVE-2026-5721
The wpDataTables – WordPress Data Table, Dynamic Tables & Table Charts Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 6.5.0.4. This is due to insufficient input sanitization and output escaping in the prepareCellOutput() method of the LinkWDTColumn, ImageWDTColumn, and EmailWDTColumn classes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, given that they can trick an Administrator into importing data from an attacker-controlled source and the affected column types (Link, Image, or Email) are configured.

Potential Impact
Severity is MEDIUM (CVSS 4.7). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.
Exploitability Assessment
Exploitability is assessed as High based on remote code execution potential, low-bar exploit prerequisites.
Primary risk drivers: remote code execution potential, low-bar exploit prerequisites
Mitigation Recommendations
Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.
Detection & Monitoring
Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.
Business Impact Lens
AI risk score 56/100 (Elevated, High) with priority P3 Priority. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
