Simple Login Guard – Monitor & Block Attempts Security & Risk Analysis

The simple-login-guard v1.0.2 plugin exhibits a strong security posture based on the provided static analysis. It demonstrates excellent security practices with 100% output escaping, no identified dangerous functions, file operations, or external HTTP requests. The presence of nonce checks (3) and capability checks (4) indicates an effort to protect against common WordPress attack vectors. Furthermore, the majority of SQL queries (80%) utilize prepared statements, which is a significant mitigation against SQL injection vulnerabilities. The complete absence of known CVEs and historical vulnerabilities further reinforces its current safety. The taint analysis also reveals no unsanitized paths or critical/high severity flows, suggesting no readily exploitable data handling issues.

While the plugin shows significant strengths in its code quality and vulnerability history, the "attack surface" metric is notably low, with zero identified entry points (AJAX handlers, REST API routes, shortcodes, cron events). This could either mean the plugin is extremely simple and inherently has few interaction points, or it might suggest a potential lack of functionality that would require such interaction points. Regardless, the absence of any unprotected entry points is a positive indicator. The only minor concern is that 20% of SQL queries might not be using prepared statements, which, while not a critical flaw given the low number and the overall secure coding practices, represents a small, albeit theoretical, risk if these specific queries handle untrusted input without sufficient sanitization.
