Is Formidable Anti-Spam Safe to Use in 2026?
Generally Safe
Score 85/100Formidable Anti-Spam has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The 'formidable-anti-spam' plugin v1.0 currently exhibits a seemingly strong security posture based on the provided static analysis. There are no identified AJAX handlers, REST API routes, shortcodes, or cron events that could serve as entry points for malicious actors. Furthermore, the code signals do not indicate the presence of dangerous functions, raw SQL queries, file operations, external HTTP requests, or unexploited taint flows. The absence of any known vulnerabilities in its history also contributes to a positive initial assessment.
However, a significant concern arises from the complete lack of output escaping (0% properly escaped). This suggests that any output generated by the plugin could be vulnerable to Cross-Site Scripting (XSS) attacks, allowing attackers to inject malicious scripts into web pages viewed by other users. The absence of nonces and capability checks across all potential entry points, though currently minimal, also poses a future risk if the plugin's attack surface were to expand or if new vulnerabilities were discovered in its logic. While the current lack of vulnerabilities is a strength, the critical flaw in output escaping overshadows the other positive indicators, demanding immediate attention.
