AFB – Auto Form Builder – Embed Forms on Any Website Security & Risk Analysis

The 'auto-form-builder' plugin v1.1.6 exhibits a generally good security posture with a strong emphasis on secure coding practices. The extensive use of prepared statements for SQL queries and proper output escaping for almost all outputs are significant strengths. The plugin also demonstrates a good understanding of WordPress security by incorporating a substantial number of nonce and capability checks. However, there are notable concerns stemming from the attack surface. The presence of 30 AJAX handlers, with 4 of them lacking authentication checks, presents a potential entry point for unauthorized actions if these handlers are not properly secured by other means. Additionally, the taint analysis revealed 2 high-severity flows with unsanitized paths, indicating a risk of potential vulnerabilities if user-supplied data is not strictly validated and sanitized before being used in sensitive operations, particularly in file operations where unsanitized paths can lead to directory traversal or other file system manipulation attacks. The complete absence of any recorded CVEs or past vulnerabilities is a positive sign, suggesting diligent maintenance and a lack of known exploitable flaws. Overall, while the plugin has a strong foundation in secure coding, the identified vulnerabilities in the attack surface and taint analysis require immediate attention to mitigate potential risks.
