Responsive Mobile-Friendly Tooltip Security & Risk Analysis

The 'responsive-mobile-friendly-tooltip' plugin version 1.6.6 exhibits a mixed security posture. On the positive side, the static analysis reveals no immediately exploitable vulnerabilities from the attack surface. All SQL queries are prepared, and all output is properly escaped, indicating good development practices in these areas. The absence of external HTTP requests and taint flows is also a positive sign. However, there are several areas of concern.

The plugin has a history of vulnerabilities, with one known unpatched medium severity CVE related to Cross-Site Scripting. This indicates a recurring issue with input sanitization or output encoding in past versions, and the fact that it's unpatched is a significant risk. Furthermore, the plugin lacks nonce checks entirely, and while capability checks are present, their effectiveness on the single shortcode entry point is not explicitly detailed. The presence of file operations without clear context on their sanitization or purpose also warrants caution.

In conclusion, while the current version shows improvements in some secure coding practices, the unpatched medium CVE and the absence of nonce checks significantly undermine its security. The plugin has demonstrated a past tendency towards XSS vulnerabilities, and the current lack of protection for its sole entry point is a weakness that could be exploited, especially if future vulnerabilities arise in how it handles user-provided data within its shortcode.
