Security readout for executives and security teams
Plain-English summary
CVE-2026-1307 is a medium-severity sensitive information disclosure issue in the WordPress Ninja Forms plugin through version 3.14.1. An authenticated user with Contributor-level access or higher may be able to obtain an authorization token exposed through the block editor/admin script loading path and use it to view form submissions for arbitrary forms. Those submissions may contain personal or business-sensitive data.
Executive priority
Treat as a near-term remediation item. Prioritize sites that collect sensitive form submissions or allow multiple Contributor+ users. The issue is not currently supported as actively exploited in the provided sources, but the confidentiality impact is high if abused.
Technical view
The vulnerability affects Ninja Forms - The Contact Form Builder That Grows With You for WordPress in versions up to and including 3.14.1. The source bundle attributes the issue to a callback function for the admin_enqueue_scripts action handler in blocks/bootstrap.php. The exposure can disclose an authorization token to authenticated Contributor+ users, enabling access to form submissions outside the user’s intended authorization boundary. CVSS 3.1 score is 6.5 with vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N and CWE-200.
Likely exposure
WordPress sites running Ninja Forms versions up to and including 3.14.1 are the relevant exposure population, especially sites that allow Contributor, Author, Editor, or other non-admin accounts and collect sensitive information through forms. Sites with only trusted administrators and no sensitive submissions have lower practical risk, but the affected version should still be reviewed.
Exploitation context
No active exploitation is supported by the provided bundle. KEV is false, and the bundle does not include a source indicating exploitation in the wild. Exploitation requires an authenticated WordPress account with Contributor-level access or higher; the reported impact is unauthorized viewing of form submissions, not code execution or service disruption.
Researcher notes
Assessment is based only on the supplied CVE source bundle. The bundle includes a Wordfence vulnerability reference and a WordPress plugin Trac changeset, but it does not explicitly provide a fixed version number beyond identifying versions up to and including 3.14.1 as affected. No exploit code, payloads, or active exploitation claims are included.
Mitigation direction
- Inventory WordPress installations using Ninja Forms and identify any instances running version 3.14.1 or earlier.
- Check official vendor/plugin guidance and update to a vendor-fixed release newer than the affected range where available; do not assume a specific fixed version from this bundle alone.
- Restrict Contributor-level and higher WordPress accounts to trusted users only, and remove or downgrade accounts that do not require dashboard/block editor access.
- Review Ninja Forms submissions for sensitive data exposure risk and consider rotating or minimizing retained sensitive form data where operationally feasible.
- Review access logs and WordPress user activity for unusual submission access by non-administrative users.
Validation and detection
- Confirm the installed Ninja Forms version on each WordPress site and flag versions up to and including 3.14.1.
- After applying vendor guidance or an update, verify that non-admin Contributor-level users cannot access arbitrary Ninja Forms submissions.
- Review the block editor/admin script behavior for affected pages to confirm sensitive authorization tokens are no longer exposed to Contributor-level users.
- Validate that role assignments follow least privilege, especially on sites with external contributors or shared editorial accounts.
- Document findings, remediation date, plugin version after remediation, and any evidence of suspicious access.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
