SurveyJS: Drag & Drop Form Builder Security & Risk Analysis

The SurveyJS plugin v2.5.3 exhibits a mixed security posture. On the positive side, the static analysis reveals a good implementation of security best practices, with a high percentage of SQL queries using prepared statements and output escaping. The plugin also demonstrates a robust use of nonces and capability checks across its code signals. The total entry points are minimal, and critically, all identified entry points appear to be protected, suggesting a strong defensive design against direct access vulnerabilities. Furthermore, the absence of critical or high severity taint flows and dangerous functions is a very encouraging sign of secure coding.

However, the plugin's vulnerability history is a significant concern. With 9 known CVEs, including 2 high and 7 medium severity vulnerabilities, it indicates a recurring pattern of security flaws. The types of past vulnerabilities, such as CSRF, XSS, missing authorization, and unrestricted file uploads, suggest that attackers have previously found ways to exploit the plugin in various ways. While there are currently no unpatched CVEs, the historical prevalence of these issues raises questions about the overall robustness of the security development lifecycle for this plugin. The last vulnerability being recorded in the future (2026-01-23) is also an anomaly that needs further investigation but does not directly impact current risk based on provided data.

In conclusion, SurveyJS v2.5.3 has strong internal security measures like prepared statements and output escaping, with a low immediate attack surface. However, its extensive history of medium and high severity vulnerabilities is a considerable risk. Users should be aware that despite current lack of unpatched issues, the plugin has proven susceptible to various attacks in the past, demanding careful monitoring and prompt updates when new vulnerabilities are disclosed.
