Is Duplicate Content Cure Safe to Use in 2026?
Use With Caution
Score 63/100Duplicate Content Cure has 1 unpatched vulnerability. Evaluate alternatives or apply available mitigations.
The "duplicate-content-cure" plugin v1.0 exhibits a mixed security posture. While the static analysis indicates a very small attack surface with no identified AJAX handlers, REST API routes, shortcodes, or cron events, there are significant concerns regarding output escaping and its vulnerability history. The lack of any output escaping on the two identified outputs is a critical weakness, leaving the plugin susceptible to Cross-Site Scripting (XSS) attacks. The presence of one unpatched medium severity CVE, historically a Cross-Site Request Forgery (CSRF) vulnerability, further highlights areas of weakness that require immediate attention. The plugin does demonstrate some good practices, such as 100% of SQL queries using prepared statements and a capability check, but these are overshadowed by the unaddressed vulnerabilities and the output escaping issue.
Key Concerns
- Unpatched CVE (medium severity)
- Output escaping is not properly handled
- No nonce checks implemented
