Is Mailchimp List Subscribe Form Safe to Use in 2026?
Generally Safe
Score 99/100Mailchimp List Subscribe Form has a strong security track record. Known vulnerabilities have been patched promptly.
This plugin exhibits a generally strong security posture, with a significant emphasis on secure coding practices. The static analysis reveals a robust implementation of security measures, including a high percentage of properly escaped output, the complete absence of raw SQL queries, and a comprehensive use of nonce and capability checks across its entry points. The lack of dangerous functions and file operations further contributes to its security. However, the presence of three flows with unsanitized paths, although not rated as critical or high severity by the taint analysis, warrants attention as these could potentially lead to unexpected behavior or security vulnerabilities if exploited in specific contexts. The plugin's vulnerability history, while showing only one past medium-severity CVE, has a recent date, suggesting that historical issues have been addressed. The fact that there are no currently unpatched vulnerabilities is a positive indicator. Overall, the plugin demonstrates good security fundamentals, but the identified unsanitized paths represent a minor area of concern that should be monitored and ideally mitigated.
