Easy Currency Converter Plugin Security & Risk Analysis

The "easy-currency-converter" v1.5.2 plugin exhibits significant security concerns, primarily stemming from its unprotected attack surface and insecure coding practices. A substantial portion of its entry points, specifically 5 out of 7, lack authentication checks, making them prime targets for unauthorized access and manipulation. The presence of unsanitized paths in taint analysis, even without reaching critical severity, signals potential risks for path traversal vulnerabilities. Furthermore, the plugin's reliance on raw SQL queries without prepared statements is a serious oversight, opening the door to SQL injection attacks. The extremely low percentage of properly escaped output (6%) indicates a high likelihood of cross-site scripting (XSS) vulnerabilities, allowing attackers to inject malicious scripts into user sessions.

While the plugin has no recorded vulnerability history, this absence should not be mistaken for inherent security. Instead, it might indicate a lack of rigorous historical security auditing or that past vulnerabilities were not publicly disclosed or patched. The use of dangerous functions like `create_function` is a red flag, as it can lead to code execution vulnerabilities if not handled with extreme care. The overall security posture is weak, with several fundamental security controls missing or poorly implemented. The significant number of unprotected entry points and the poor output escaping are major weaknesses that require immediate attention.
