# CVE-2026-15286: Gutenberg Blocks with AI by Kadence WP – Page Builder Features \<= 3.5.32 - Incorrect Authorization to Authenticated (Contributor+) Post Publication

- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-07-10 · Updated: 2026-07-10

## Affected

- stellarwp Kadence Blocks — Page Builder Toolkit for Gutenberg Editor: through 3.5.32

## Description

The Gutenberg Blocks with AI by Kadence WP – Page Builder Features plugin for WordPress is vulnerable to unauthorized post publication in all versions up to, and including, 3.5.32 due to a misconfigured capability check on the 'get_items_permission_check' function permission callback of the 'process_pattern' REST API endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create and immediately publish posts of any type (including pages), bypassing the standard WordPress review workflow where contributors must submit posts for administrator approval.
