MK Auto Youtube Player Security & Risk Analysis

The plugin "mk-auto-youtube-player" v2014.11.10 presents a mixed security posture. On the positive side, there are no known CVEs associated with this plugin and it does not appear to perform file operations or external HTTP requests, which are common sources of vulnerabilities. The plugin also utilizes prepared statements for all its SQL queries, which is a strong security practice.

However, the static analysis reveals significant concerns. The plugin has a critical weakness in its output escaping, with 100% of outputs not being properly escaped. This could lead to Cross-Site Scripting (XSS) vulnerabilities if user-supplied data is displayed without sanitization. Furthermore, the taint analysis indicates flows with unsanitized paths, suggesting potential vulnerabilities related to how data is processed within the plugin. The absence of nonce checks and capability checks on its single shortcode entry point is also a notable concern, as it opens the door for potential unauthorized actions or data manipulation if the shortcode's functionality is not adequately protected.

While the plugin's vulnerability history is clean, this is likely due to its age and lack of updates rather than inherent robust security. The lack of modern security checks like nonce and capability checks, coupled with the unescaped output and taint flows, indicates a substantial risk for XSS and potentially other injection-type attacks. The overall security is compromised by these fundamental flaws, outweighing the strengths of its SQL practices and lack of known CVEs.
