Hash Form – Drag & Drop Form Builder Security & Risk Analysis

The "hash-form" plugin version 1.3.8 exhibits a mixed security posture. While it demonstrates strong practices in areas like SQL prepared statements and output escaping, with 97% and 98% respectively, several concerning aspects remain. The presence of 4 AJAX handlers without authentication checks presents a significant attack surface, potentially allowing unauthorized users to trigger critical functionalities. Furthermore, the static analysis identified the use of dangerous functions like `unserialize`, which can be a vector for deserialization vulnerabilities if not handled with extreme care and sanitization.

The plugin's vulnerability history is a notable concern, with a total of 5 known CVEs, including one critical, one high, and three medium severity vulnerabilities. The recurring types of vulnerabilities such as CSRF, Missing Authorization, Unrestricted Upload, and Deserialization of Untrusted Data suggest a pattern of underlying weaknesses in how user inputs and sensitive operations are handled. The fact that there are no currently unpatched vulnerabilities is positive, but the historical prevalence of severe issues warrants caution and diligent monitoring.

In conclusion, "hash-form" v1.3.8 has strengths in its implementation of secure coding practices like prepared statements and output escaping. However, the unprotected AJAX endpoints, the use of `unserialize`, and a history of significant vulnerabilities, particularly those related to authorization and input validation, introduce substantial risks. Users should be aware of these potential weaknesses and ensure the plugin is kept up-to-date with any security patches. The plugin's historical vulnerability trend suggests a need for developers to rigorously address input validation and authorization mechanisms in future updates.
