Flamingo exposes contact-form taxonomy data to contributors

Flamingo through 2.6.2 applies its flamingo_map_meta_cap() restrictions to the plugin's admin interface but not to WordPress core APIs. A Contributor can use XML-RPC wp.getTerms or admin-ajax ajax-tag-search to enumerate Contact Form 7-derived channel names, submission counts, and contact tag names that the account is not authorized to view.

NVD score Pending NVD has not published its own CVSS assessment.

Component: Flamingo
Plugin slug: flamingo
Affected: <= 2.6.2
Safe version: 2.6.3
Published: Sep 07, 2026
Weakness: CWE-862 — Missing Authorization

This CVE was published Sep 07, 2026 and is one of 1 known issue for this plugin.

What to do

Update, patch or deactivate.

Update Flamingo to 2.6.3 or later. Review Contributor access and treat exposed form titles, workflow identifiers, submission counts, and contact tags as potentially disclosed.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Flamingo plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to enumerate taxonomy terms including channel names derived from Contact Form 7 form titles that may reveal internal form purposes, department names, or workflow identifiers, as well as submission counts per channel and contact tag names. The plugin's flamingo_map_meta_cap() filter restricts access to Flamingo's admin UI but does not extend to WordPress core APIs such as XML-RPC wp.getTerms and admin-ajax ajax-tag-search.
