CVE-2026-5111
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 2.10.0. This is due to insufficient input validation and output escaping on Hidden Product field values when used inside Repeater fields, where repeater subfields bypass state validation checks and the Hidden Product validate() method only validates the quantity field while ignoring the product name field that is later output without proper escaping in the get_value_entry_detail() method. This makes it possible for unauthenticated attackers to inject arbitrary web scripts through form submissions that will execute whenever an administrator views the entry details.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Gravity Forms plugin up to v2.10.0 contains a stored XSS vulnerability in Hidden Product fields used within Repeater fields. The validate() method only checks the quantity field while ignoring the product name field, and get_value_entry_detail() outputs this value without escaping, allowing unauthenticated attackers to inject malicious scripts via form submissions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Gravity Forms versionLocate the Gravity Forms plugin file (typically in /wp-content/plugins/gravityforms/ or via WordPress admin > Plugins) and check the version number in the plugin header or changelogAffected if Version is 2.10.0 or lower (versions after 2.10.0 contain the fix)
-
Identify forms using Repeater fieldsReview all forms in the Gravity Forms admin panel and check if any form contains a Repeater field (field type: Repeater)Affected if At least one form contains a Repeater field
-
Check for Hidden Product fields inside RepeatersFor each form with a Repeater field, inspect the Repeater's field list to determine if it contains a Hidden Product field (field type: Product > Hidden)Affected if A Hidden Product field exists within a Repeater field in any form
-
Verify unauthenticated form submission is allowedCheck the form settings > Restrictions tab to see if the form accepts submissions from unauthenticated users (Require Login is unchecked)Affected if Form with Hidden Product in Repeater allows anonymous submissions
-
Inspect recent form entries for suspicious contentReview Gravity Forms > Entries for forms with Hidden Product fields in Repeaters; examine the entry detail values in the product name field for unescaped HTML/script tagsAffected if Entry values in Hidden Product fields contain unescaped HTML or script content
Environment is affected if Gravity Forms version is 2.10.0 or lower AND any form contains a Hidden Product field within a Repeater field that accepts unauthenticated submissions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate to a version beyond 2.10.0 where the vendor has addressed input validation and output escaping for Hidden Product fields in repeater contexts. Until then, restrict form creation/management to trusted users and consider disabling repeater fields with Hidden Product fields.
A version newer than 2.10.0 (specific fixed release available from Gravity Forms)
- 1. Backup your WordPress site and database before making any changes.
- 2. Navigate to the Plugins section in WordPress admin dashboard.
- 3. Locate the Gravity Forms plugin and check the current version installed.
- 4. If the installed version is 2.10.0 or earlier, update the plugin to the latest available version.
- 5. After updating, verify the plugin version has changed to confirm the update was successful.
- 6. Test form submissions with Hidden Product fields inside Repeater fields to ensure functionality remains intact.
- 7. Review entry details for any submissions to confirm the XSS vulnerability is remediated.
