f(x) SEO Security & Risk Analysis
wordpress.org/plugins/fx-seoVery simple SEO plugin.
Is f(x) SEO Safe to Use in 2026?
Generally Safe
Score 85/100f(x) SEO has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The fx-seo plugin v1.1.0 exhibits a generally good security posture based on the static analysis. The absence of identified dangerous functions, file operations, external HTTP requests, and SQL queries not using prepared statements are positive indicators. Furthermore, the lack of any recorded CVEs, past or present, suggests a relatively stable security history for this plugin. The static analysis also indicates a zero attack surface and zero taint flows, which are excellent signs of well-secured code entry points and data handling. However, a notable concern is the low percentage of properly escaped output (32%). This could leave the plugin vulnerable to cross-site scripting (XSS) attacks if user-supplied data is displayed without adequate sanitization, particularly if any of the output points are indirectly exposed through other means. While the current attack surface appears minimal, a low output escaping rate is a significant weakness that warrants attention.
