Last-USERS-Dashboard-Widget Security & Risk Analysis

The 'last-users-dashboard-widget' plugin version 0.305 exhibits a generally strong security posture from a static analysis perspective, with no identified attack surface through common entry points like AJAX, REST API, shortcodes, or cron events. The absence of dangerous functions, file operations, and external HTTP requests further contributes to this positive assessment. The code also shows a commitment to security by implementing capability checks on its SQL queries.

However, a significant concern arises from the complete lack of output escaping. This means that any data rendered by the plugin could potentially be manipulated by an attacker, leading to cross-site scripting (XSS) vulnerabilities. The 50% of SQL queries not using prepared statements also represent a potential SQL injection risk, although the total number of queries is low. The absence of nonce checks, while not directly linked to an exposed attack surface in this specific analysis, is generally a good practice for securing AJAX actions and could be a missed opportunity for layered security.

The plugin's vulnerability history is a significant strength, with zero recorded CVEs of any severity. This suggests a history of responsible development and a lack of exploitable vulnerabilities discovered to date. In conclusion, while the plugin benefits from a minimal attack surface and a clean vulnerability history, the critical lack of output escaping and the presence of non-prepared SQL queries are notable weaknesses that require immediate attention.
