MyStem EDD Security & Risk Analysis

The mystem-edd v1.1 plugin exhibits a generally strong security posture based on the provided static analysis. The absence of dangerous functions, the exclusive use of prepared statements for SQL queries, and the presence of nonce and capability checks are positive indicators. The code's adherence to output escaping for a significant majority of its outputs (69%) suggests a good effort towards preventing cross-site scripting vulnerabilities.

However, the analysis also reveals potential areas for improvement. While the attack surface is currently small and appears to have no unprotected entry points, the presence of three shortcodes means there are potential interaction points that could be exploited if not properly secured internally. The 31% of outputs that are not properly escaped represent a moderate risk of cross-site scripting (XSS) vulnerabilities, which could be leveraged to compromise user sessions or inject malicious content.

The plugin's vulnerability history, showing zero known CVEs and no past vulnerabilities, is a positive sign. This indicates a history of stability and potentially good security practices in previous development cycles. Overall, mystem-edd v1.1 demonstrates a good foundation with its use of security best practices, but the unescaped output percentages warrant attention to fully mitigate potential XSS risks.
