HEXAM Security & Risk Analysis

The 'hexam' v1.3 plugin exhibits several significant security concerns despite having no recorded vulnerability history. The static analysis reveals a complete lack of output escaping, meaning all dynamic data rendered to the user interface is susceptible to Cross-Site Scripting (XSS) attacks. This is a critical oversight that significantly undermines the plugin's security posture. Furthermore, the presence of two taint flows with unsanitized paths indicates a potential for arbitrary code execution or other severe vulnerabilities if these flows are exploitable. While the plugin has a small attack surface and no known CVEs, the identified code quality issues present a substantial risk. The absence of nonce and capability checks in its entry points (shortcodes) is also worrying, though the taint analysis did not explicitly link these to critical vulnerabilities. The plugin's security is compromised by its poor handling of output and potential for unsanitized data flow, outweighing the benefit of no known historical vulnerabilities.
