Simple Contact Us Form Widget Security & Risk Analysis

The 'simple-contact-us-form-widget' plugin version 2.2.1 exhibits a generally strong security posture based on the provided static analysis. The absence of dangerous functions, file operations, and external HTTP requests, coupled with the use of prepared statements for all SQL queries and a high percentage of properly escaped outputs, are positive indicators. The presence of nonce and capability checks, while not exhaustive, further contribute to a more secure design. The plugin has no recorded vulnerabilities, which suggests a history of stable and secure development. However, the lack of any capability checks across the identified entry points (AJAX handlers and shortcodes) presents a potential concern. While the static analysis did not reveal any critical taint flows or unsanitized paths, the absence of explicit authorization checks on all entry points means that unauthorized users *could* potentially trigger these actions if an attacker finds a way to bypass WordPress's default permission system or if the plugin's intended use case doesn't strictly require authorization for these actions. This is a weakness that, while not currently exploited, leaves room for potential future issues if the plugin's functionality evolves or if new attack vectors are discovered.
