CVE-2026-2440SurveyJS: Drag & Drop Form Builder <= 2.5.3 - Unauthenticated Stored Cross-Site Scripting
High 7.2
In plain English
A high-severity cross-site scripting in SurveyJS: Drag & Drop Form Builder from devsoftbaltic. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 22% of all known vulnerabilities).
Official description
The SurveyJS plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.5.3 via survey result submissions. This is due to insufficient input sanitization and output escaping. The public survey page exposes the nonce required for submission, allowing unauthenticated attackers to submit HTML-encoded payloads that are decoded and rendered as executable HTML when an administrator views survey results, leading to stored XSS in the admin context.
