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.

AI Analysis

Impact

The SurveyJS Drag & Drop Form Builder plugin for WordPress is vulnerable to stored cross‑site scripting. Unsanitized survey submissions allow an attacker to inject HTML‑encoded payloads that are saved and later rendered as executable code when an administrator views survey results. This flaw, identified as CWE‑79, can lead to arbitrary script execution within the administrative interface, potentially compromising confidentiality, integrity, or availability of the site.

Affected Systems

The vulnerability affects the devsoftbaltic SurveyJS Drag & Drop Form Builder plugin for WordPress in all publicly released versions up to and including 2.5.3. Sites running any of these releases are at risk if the plugin remains active.

Risk and Exploitability

The CVSS score of 7.2 indicates moderate‑to‑high severity. An EPSS score is not available and the flaw is not listed in the CISA KEV catalog, so the likelihood of exploitation is uncertain. The attack vector is inferred to be unauthenticated: the public survey page exposes the required nonce, enabling any visitor to submit malicious payloads that are stored and later rendered in the admin context. No additional prerequisites or privileges are required beyond the ability to submit a survey response.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update SurveyJS to a version newer than 2.5.3 that removes the stored XSS flaw.
  • If a newer version is not available, disable the survey result submission endpoint or block submissions from unauthenticated users.
  • If the plugin is not needed, deactivate or uninstall SurveyJS Drag & Drop Form Builder entirely.
  • As a temporary safeguard, apply a strict content security policy to the administrator area to prevent execution of injected scripts.
