CVE-2025-14846: SocialChamp WordPress Plugin CSRF Flaw

CVE-2025-14846 Overview

The SocialChamp with WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in all versions up to, and including, 1.3.3. This vulnerability exists due to missing nonce validation on the wpsc_settings_tab_menu function. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Critical Impact

Unauthenticated attackers can manipulate plugin settings through social engineering, potentially compromising social media integration configurations and site security.

Affected Products

• SocialChamp with WordPress plugin versions up to and including 1.3.3
• WordPress installations using the affected plugin versions
• auto-post-to-social-media-wp-to-social-champ plugin

Technical Details for CVE-2025-14846

Vulnerability Analysis

This Cross-Site Request Forgery (CWE-352) vulnerability stems from the plugin's failure to implement proper nonce validation on the settings management function. In WordPress, nonces (number used once) are security tokens that verify whether a request originated from a legitimate source within the WordPress admin interface. Without this validation, the plugin cannot distinguish between authentic administrator actions and forged requests initiated by malicious third parties.

The vulnerable function wpsc_settings_tab_menu processes settings changes without verifying the request's authenticity. This architectural flaw allows attackers to craft malicious web pages or links that, when visited by an authenticated administrator, execute unauthorized settings modifications on the WordPress site.

Root Cause

The root cause of this vulnerability is the absence of nonce verification in the wpsc_settings_tab_menu function located in class-wp-socialchamp-settings-init.php. WordPress provides built-in functions like wp_verify_nonce() and check_admin_referer() specifically to prevent CSRF attacks, but the plugin developers failed to implement these security controls before processing settings changes.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker must craft a malicious HTML page containing a hidden form or JavaScript that submits forged requests to the vulnerable endpoint. The attacker then needs to trick a logged-in WordPress administrator into visiting this malicious page while their session is active.

The exploitation scenario typically involves:

1. Attacker identifies a WordPress site using the vulnerable SocialChamp plugin
2. Attacker creates a malicious webpage with a forged request targeting the settings endpoint
3. Attacker delivers the malicious link to the site administrator via email, social media, or other channels
4. When the administrator clicks the link while logged into WordPress, the forged request executes with their privileges
5. Plugin settings are modified without the administrator's knowledge or consent

Detection Methods for CVE-2025-14846

Indicators of Compromise

• Unexpected changes to SocialChamp plugin settings without administrator action
• Administrator reports of clicking unfamiliar links shortly before settings were modified
• Web server logs showing POST requests to plugin settings endpoints with unusual referrer headers
• Multiple settings changes occurring in rapid succession from different IP addresses

Detection Strategies

• Review WordPress admin activity logs for unauthorized settings modifications to the SocialChamp plugin
• Monitor HTTP referrer headers for settings change requests originating from external domains
• Implement Content Security Policy (CSP) headers to detect and block cross-origin form submissions
• Use WordPress security plugins that log and alert on plugin configuration changes

Monitoring Recommendations

• Enable comprehensive logging of all WordPress admin actions and plugin settings changes
• Configure alerts for settings modifications occurring outside normal administrative workflows
• Monitor for suspicious outbound connections that may indicate compromised social media credentials
• Regularly audit plugin configurations against known-good baseline settings

How to Mitigate CVE-2025-14846

Immediate Actions Required

• Update the SocialChamp with WordPress plugin to a version newer than 1.3.3 if available
• Review current plugin settings for any unauthorized modifications
• Educate site administrators about CSRF attack vectors and safe browsing practices
• Consider temporarily disabling the plugin until a patched version is available

Patch Information

Site administrators should check for updates to the SocialChamp with WordPress plugin through the WordPress admin dashboard or the official WordPress plugin repository. For detailed vulnerability information, refer to the Wordfence Vulnerability Report.

Workarounds

• Implement additional authentication layers such as two-factor authentication for WordPress administrators
• Use a Web Application Firewall (WAF) with CSRF protection rules to filter malicious requests
• Restrict administrative access to trusted IP addresses only
• Configure browser extensions that block cross-site request submissions

# Configuration example - Add to wp-config.php to help mitigate CSRF risks
# Force admin SSL to ensure session cookies are transmitted securely
define('FORCE_SSL_ADMIN', true);

# Limit login attempts and session duration
define('AUTOSAVE_INTERVAL', 120);
define('WP_POST_REVISIONS', 5);
