User Login Statistics Security & Risk Analysis

The "user-login-stat" plugin version 0.1 presents a mixed security profile. On the positive side, the static analysis indicates a very small attack surface with no identified AJAX handlers, REST API routes, shortcodes, or cron events that are directly exposed. Furthermore, there are no identified dangerous functions, file operations, external HTTP requests, or bundled libraries, which are all good signs of a secure codebase. The plugin also has no known historical vulnerabilities (CVEs), which suggests a relatively clean past.

However, significant concerns arise from the lack of security checks in the code. The absence of nonce checks and capability checks is particularly worrying, especially considering that there are SQL queries being executed. Although 40% of SQL queries use prepared statements, this still leaves a portion that may not, and without proper capability checks, an authenticated user could potentially execute these queries. Moreover, only 25% of output is properly escaped, indicating a risk of Cross-Site Scripting (XSS) vulnerabilities where user-supplied data might be reflected in the output without adequate sanitization.

In conclusion, while the plugin benefits from a minimal attack surface and a clean vulnerability history, the lack of fundamental security mechanisms like nonce and capability checks, coupled with insufficient output escaping, introduces notable risks. The presence of SQL queries without guaranteed authorization mechanisms is a critical weakness. Future development should prioritize implementing robust access controls and proper output sanitization to mitigate these identified vulnerabilities.
