Posts Viewed Recently Security & Risk Analysis

The "posts-viewed-recently" plugin v1.3.2 presents a generally good security posture based on the provided static analysis. The absence of dangerous functions, file operations, external HTTP requests, and SQL queries executed without prepared statements are positive indicators. The limited attack surface, with only one shortcode and no unprotected AJAX handlers or REST API routes, further contributes to its security. However, a significant concern arises from the low percentage of properly escaped output (25%). This indicates that a substantial portion of the plugin's output may be vulnerable to Cross-Site Scripting (XSS) attacks, especially if user-supplied data is displayed without adequate sanitization.

The vulnerability history shows no known CVEs, which is a strong positive sign. This suggests a history of secure development or effective patching by developers. The lack of recorded common vulnerability types reinforces this. Despite the strong vulnerability history, the unescaped output remains a significant weakness that could be exploited. The overall conclusion is that while the plugin benefits from a minimal attack surface and a clean vulnerability record, the unescaped output presents a tangible risk that should be addressed.
