Security readout for executives and security teams
Plain-English summary
CVE-2026-1901 affects the QuestionPro Surveys WordPress plugin up to and including version 1.0. A logged-in user with Contributor-level access or higher could save malicious script through the plugin shortcode. That script may run when someone views the affected page, potentially exposing user data or enabling actions in the viewer’s browser.
Executive priority
Treat as a medium-priority web application issue. Prioritize sites with multiple content contributors or public user registration. It is less severe than unauthenticated takeover, but stored XSS can affect administrators and visitors if abused.
Technical view
The issue is stored cross-site scripting in the `questionpro` shortcode attributes, caused by insufficient input sanitization and output escaping. Wordfence rates it CVSS 6.4. Exploitation requires authenticated WordPress access at Contributor level or above, but no user interaction is required beyond visiting an injected page.
Likely exposure
Exposure is limited to WordPress sites using the QuestionPro Surveys plugin version 1.0 or earlier, especially where untrusted users can create or edit content as Contributors or higher.
Exploitation context
The source bundle does not indicate known active exploitation, and the CVE is not listed as KEV. The practical risk rises on multi-author sites, membership sites, or compromised contributor accounts.
Researcher notes
The description states all versions up to and including 1.0 are vulnerable. The affected-version metadata in the bundle appears incomplete or inconsistent, so validate against Wordfence and plugin repository evidence before making asset-wide conclusions.
Mitigation direction
- Identify whether QuestionPro Surveys is installed and its version.
- Review vendor and WordPress plugin guidance for an updated or fixed release.
- Restrict Contributor and higher content permissions to trusted users only.
- Remove or disable the plugin if it is unused or cannot be safely updated.
- Review existing content using the QuestionPro shortcode for suspicious attributes.
Validation and detection
- Inventory WordPress sites for the QuestionPro Surveys plugin.
- Confirm installed plugin version is not 1.0 or earlier.
- Check pages and posts containing the `questionpro` shortcode.
- Review WordPress users with Contributor, Author, Editor, or Administrator roles.
- Monitor for unexpected scripts executing on pages using the shortcode.
