Multiple Currencies for Paid Memberships Pro Security & Risk Analysis

The static analysis of "pmpro-multiple-currencies" v0.0.5 reveals a plugin with a very small attack surface, reporting zero AJAX handlers, REST API routes, shortcodes, and cron events. Furthermore, the code signals indicate no dangerous functions, no raw SQL queries, and no external HTTP requests. This suggests a diligent approach to core security principles within the analyzed code. However, a notable concern is the output escaping, where 33% of outputs are not properly escaped, potentially leaving the plugin vulnerable to cross-site scripting (XSS) if user-supplied data is directly reflected in the output without proper sanitization.

The vulnerability history is clean, with no recorded CVEs. This, combined with the absence of critical taint flows, contributes to a generally positive security posture. The lack of known vulnerabilities and the clean taint analysis suggest that the plugin developers have historically been proactive or fortunate in avoiding exploitable issues. While the small attack surface and absence of SQL injection risks are strengths, the unescaped output remains a potential weakness that requires attention to ensure comprehensive security.
