CVE-2026-25391: 
WordPress vulnerability analysis and mitigation

CVE-2026-25391 is a Missing Authorization vulnerability in the WP Grids WP Wand WordPress plugin (slug: ai-content-generation) that allows authenticated attackers with low-level privileges to exploit incorrectly configured access control security levels. The vulnerability affects WP Wand versions from n/a through 1.3.07. It was published on February 19, 2026, and carries a CVSS v3.1 base score of 5.4 (Medium) (Feedly).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify that a requesting user has the necessary permissions before executing sensitive actions related to AI content generation. The attack vector is network-based, requires low privileges (authenticated user), no user interaction, and low attack complexity. Because authorization checks are absent or misconfigured, a low-privileged WordPress user (e.g., subscriber or contributor) can invoke restricted plugin functionality that should be limited to higher-privileged roles (Feedly).

Successful exploitation results in low integrity and low availability impacts, with no confidentiality impact. An authenticated attacker could abuse the plugin's AI content generation features beyond their intended permission level — for example, triggering unauthorized content creation or modification actions, or causing unintended resource consumption on the WordPress site. The scope is unchanged, meaning the impact is confined to the vulnerable component itself (Feedly).

The EPSS score for CVE-2026-25391 is approximately 0.017% (0.000170), indicating a very low probability of exploitation in the wild at this time. No public proof-of-concept exploit code, active in-the-wild exploitation, threat actor attribution, or CISA KEV catalog listing has been identified for this vulnerability. Exploitation requires a valid low-privileged account on the target WordPress installation (Feedly).

1. Reconnaissance: Identify WordPress sites running the WP Wand plugin (slug: ai-content-generation) version 1.3.07 or earlier, using tools like WPScan or by checking the plugin's readme.txt file at https://target.com/wp-content/plugins/ai-content-generation/readme.txt.
2. Obtain low-privileged account: Register or obtain credentials for a low-privileged WordPress account (e.g., subscriber role) on the target site.
3. Identify unprotected AJAX/REST endpoints: Enumerate the plugin's registered WordPress AJAX actions or REST API endpoints that lack proper capability checks, typically found by reviewing the plugin's source code or by intercepting authenticated requests.
4. Send unauthorized request: Craft and send an authenticated HTTP request (with valid nonce and session cookies) to the identified unprotected endpoint, invoking a restricted action such as triggering AI content generation or modifying plugin settings.
5. Achieve objective: Observe that the action executes successfully despite the user lacking the required permissions, resulting in unauthorized content manipulation or resource consumption (Feedly).

• Logs: WordPress access logs showing authenticated POST requests to wp-admin/admin-ajax.php with WP Wand-specific action parameters from low-privileged user accounts; unexpected REST API calls to WP Wand endpoints from subscriber or contributor accounts.
• File System: Unexpected or unauthorized AI-generated content appearing in posts/pages not created by higher-privileged users.
• Process/Application: Unusual spikes in AI content generation API usage or quota consumption not attributable to authorized editorial activity.

Users should update the WP Wand plugin to a version beyond 1.3.07 that includes proper authorization checks, once a patched release is made available by WP Grids. In the interim, site administrators should consider deactivating the plugin if it is not critical to operations, or restricting site registration to prevent untrusted users from obtaining low-privileged accounts. Monitoring WordPress user activity logs for unexpected plugin interactions is also recommended (Feedly, Patchstack).
