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.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress session with at minimum Contributor-level role on the target site (CVSS PR:L confirmed). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, score 4.3) correctly captures the bounded impact: exploitation requires network access but also an authenticated session at Contributor level or above, and the only consequence is unauthorized content integrity modification - not data exfiltration or service disruption. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker obtains or registers a Contributor-level WordPress account on a target site running Kadence Blocks ≤ 3.5.32 - either through open registration, credential theft, or social engineering. They then craft an authenticated REST API request to the `process_pattern` endpoint, which the misconfigured permission callback accepts. … |
| Remediation | Update the Kadence Blocks plugin to version 3.5.33 or later; the fix is confirmed present in SVN changeset 3445125 at plugins.trac.wordpress.org/changeset/3445125/ and is available via the standard WordPress plugin update mechanism (Dashboard > Plugins > Update Available). … Detailed patch versions, workarounds, and compensating controls in full report. |
