CVE-2026-15286 stellarwp CVE debrief

Who should care

Administrators and users with Contributor-level access and above of WordPress installations using the Gutenberg Blocks with AI by Kadence WP – Page Builder Features plugin should be aware of this vulnerability and take necessary precautions to prevent exploitation.

Technical summary

The plugin's misconfigured capability check on the 'get_items_permission_check' function permission callback of the 'process_pattern' REST API endpoint allows authenticated attackers with Contributor-level access and above to create and immediately publish posts of any type, including pages. This is possible because the capability check does not properly restrict access to the 'process_pattern' endpoint, allowing attackers to bypass the standard WordPress review workflow. As a result, attackers can create and publish posts without needing administrator approval.

Defensive priority

Medium priority due to the potential for authenticated attackers to exploit this vulnerability and create malicious content on the affected system.

Recommended defensive actions

• Update the Gutenberg Blocks with AI by Kadence WP – Page Builder Features plugin to a version beyond 3.5.32.
• Restrict Contributor-level access and above to only trusted users.
• Monitor for suspicious post publication activity.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
