Active Users List Security & Risk Analysis

The 'active-users-list' plugin v1.0 exhibits a mixed security posture. On the positive side, it has no recorded vulnerabilities (CVEs), and the static analysis reveals a limited attack surface with no identified AJAX handlers or REST API routes lacking authentication. Furthermore, there are no dangerous functions, file operations, external HTTP requests, or bundled libraries. This suggests a generally conservative approach to coding practices.

However, significant concerns arise from the code signals. The plugin uses raw SQL queries, with a concerning 67% not employing prepared statements, which is a substantial risk for SQL injection vulnerabilities. Critically, none of the identified outputs are properly escaped, leaving the plugin vulnerable to Cross-Site Scripting (XSS) attacks. The absence of nonce checks and capability checks on its single shortcode entry point further exacerbates these risks, as it allows for potential unauthorized actions or data exposure.

While the lack of a vulnerability history is a good sign, it doesn't negate the inherent risks identified in the current code. The potential for SQL injection and XSS attacks, coupled with the absence of essential security checks, means that even without past incidents, this plugin presents a significant security risk to any WordPress installation. The strengths lie in its limited attack surface and lack of known past exploits, but the weaknesses in input sanitization and output escaping are critical.
