NoSSL – protect your website Security & Risk Analysis

The 'nossl-protect-your-website' plugin v1.1 exhibits a mixed security posture. On the positive side, it demonstrates no known CVEs, a clean vulnerability history, and no external HTTP requests, indicating a generally stable and low-profile plugin. The absence of AJAX handlers, REST API routes, shortcodes, and cron events, coupled with the fact that all SQL queries use prepared statements, significantly limits its attack surface and direct database manipulation risks.

However, the static analysis reveals several concerning code signals. The presence of dangerous functions like `set_time_limit`, `unserialize`, `ini_set`, and `create_function` without any apparent authorization or capability checks presents potential risks. `unserialize` is particularly concerning as it can lead to Remote Code Execution (RCE) if used with untrusted input. The low percentage of properly escaped output (9%) suggests a high risk of Cross-Site Scripting (XSS) vulnerabilities, where malicious scripts could be injected and executed in the user's browser.

While the plugin has a clean vulnerability history, this can be misleading. The lack of detected issues might stem from a lack of in-depth analysis or testing rather than inherent security. The combination of dangerous functions and poor output sanitization, without any nonce or capability checks, creates a significant potential for exploitation. Therefore, despite its clean history, the plugin has inherent risks that require attention.
