Auto-Install Free SSL – Generate & Install Free SSL Certificates Security & Risk Analysis

The auto-install-free-ssl plugin version 4.6.1 exhibits a mixed security posture. While it demonstrates good practices in areas like SQL query handling and a lack of recorded critical vulnerabilities, significant concerns arise from its attack surface and output escaping. The presence of an unprotected AJAX handler presents a clear entry point for potential unauthorized actions or information disclosure if not properly secured by the application logic. Furthermore, the extremely low percentage of properly escaped output is a major red flag, indicating a high risk of Cross-Site Scripting (XSS) vulnerabilities that could be exploited by attackers to inject malicious code into user interfaces. The taint analysis showing a high number of flows with unsanitized paths, although not reaching critical or high severity, further reinforces the concern around input sanitization. The plugin's history of zero CVEs is positive, suggesting a generally stable codebase, but this must be weighed against the immediate risks identified in the static analysis.
