Nakiedy – system rezerwacji online Security & Risk Analysis

The "nakiedy-darmowy-system-rezerwacji-online" plugin v1.2.1 exhibits a generally strong security posture, with no known vulnerabilities or CVEs in its history. The static analysis reveals a commendable lack of dangerous functions, file operations, and external HTTP requests. Notably, all SQL queries utilize prepared statements, and there is at least one nonce and capability check implemented, suggesting an awareness of fundamental WordPress security practices. The absence of AJAX handlers, REST API routes, and shortcodes contributes to a minimal attack surface, further bolstering its security.

However, a significant concern arises from the taint analysis, which identified one flow with an unsanitized path. While this did not reach a critical or high severity in the taint analysis, it represents a potential avenue for exploitation if not properly handled. Additionally, the low percentage of properly escaped output (7%) is a notable weakness. With 27 outputs analyzed and only a small fraction correctly escaped, there is a substantial risk of Cross-Site Scripting (XSS) vulnerabilities, allowing attackers to inject malicious scripts into the user interface.

In conclusion, the plugin benefits from a clean vulnerability history and a well-controlled attack surface. The core database interactions appear secure. Nevertheless, the identified unsanitized path in the taint analysis and the widespread lack of output escaping present tangible security risks that require immediate attention. Addressing these weaknesses will significantly improve the plugin's overall security.
