On November 24, 2025, Wordfence detected an unprecedented security incident: a critical remote code execution (RCE) vulnerability in the Sneeit Framework WordPress plugin was being actively exploited in the wild.
Not just hundreds or thousands, but over 131,000 exploitation attempts targeting the Sneeit Framework plugin in just seven days. This large-scale, real-time attack campaign saw threat actors systematically targeting WordPress sites running vulnerable versions of the Sneeit Framework plugin for WordPress, leveraging this critical remote code execution vulnerability (CVE-2025-6389) to execute arbitrary code on the server and compromise sites[1][2][3].
Understanding CVE-2025-6389: A Critical Remote Code Execution Vulnerability in the Sneeit Framework Plugin
CVE-2025-6389 is a critical remote code execution vulnerability affecting all versions of the Sneeit Framework plugin for WordPress up to and including version 8.3. With a maximum CVSS score of 9.8, this vulnerability represents one of the most severe threats to WordPress security in 2025[1][2][3].
The vulnerability exists in the sneeit_articles_pagination_callback() function, which accepts unsanitized user input and then passes it through call_user_func() without proper validation or sanitization. This critical design flaw makes it possible for unauthenticated attackers to execute arbitrary PHP code on the server, completely bypassing WordPress authentication and security mechanisms[1][2].
Unlike many vulnerabilities that require some level of authentication, CVE-2025-6389 allows unauthenticated attackers to execute code on the server simply by knowing the site uses a vulnerable version of the Sneeit Framework plugin for WordPress. No login or special permissions are needed, making this flaw extremely dangerous and easy to exploit[1][2][3].
How the Exploit Works: Leveraging the Vulnerable Function to Execute Code
The vulnerability can be leveraged by sending specially crafted AJAX POST requests to the WordPress administrative endpoint wp-admin/admin-ajax.php. Attackers specify an arbitrary PHP function name and malicious arguments via POST parameters, which the vulnerable code executes directly using call_user_func() without validation[3].
Here is a simplified example of the vulnerable code pattern in the Sneeit Framework plugin for WordPress:
// Vulnerable code in Sneeit Framework plugin
$function = $_POST['callback'];
call_user_func($function, $_POST['args']); // No validation or sanitization
An attacker could exploit this by calling functions like wp_insert_user() to create new administrator accounts. These unauthorized admin accounts allow attackers to seize complete control of the WordPress site, install backdoors, upload malware, deface the site, steal sensitive data, or redirect visitors to malicious content[2][5].
The Attack Timeline: From Patch Release to Active Exploitation
The timeline of CVE-2025-6389 reveals critical lessons about WordPress security and patch management:
- June 10, 2025: Wordfence received the initial vulnerability submission for the Sneeit Framework plugin for WordPress

- November 24–December 1, 2025: Over 131,000 attack attempts recorded by Wordfence targeting the vulnerability
- December 2025 (ongoing): Exploitation continues with threat actors actively targeting vulnerable Sneeit Framework plugin installations
The critical issue: The vulnerability patch was available for over three months before attackers began actively exploiting CVE-2025-6389. Despite this ample window, thousands of WordPress sites running the vulnerable Sneeit Framework plugin remained exposed. This gap highlights the importance of timely updates, automatic patching, and proactive vulnerability management in WordPress security. Unlike a zero-day vulnerability (where no patch exists), this cyber attack campaign targeted sites that failed to apply the available vulnerability patch[1][2][3].
The Scale of the Threat: Attack Metrics and Impact on WordPress Sites
The scale of the CVE-2025-6389 cyber attack campaign underscores the systematic nature of the threat against WordPress sites running the Sneeit Framework plugin. This coordinated cyber attack demonstrates how quickly threat actors can scale exploitation once a vulnerability is disclosed:

- Approximately 18,700 attacks per day during peak exploitation
- 780 attacks per hour targeting vulnerable Sneeit Framework plugin versions
- One attack attempt every 4.6 seconds around the clock
These automated scanning and exploitation attempts target the roughly 1,700 active installations of the Sneeit Framework plugin for WordPress, making it a high-value target for threat actors seeking to leverage this critical remote code execution vulnerability[1][2][3].
What Attackers Can Do When They Exploit This Vulnerability
Successful exploitation of CVE-2025-6389 grants attackers the ability to execute arbitrary code on the server, enabling a wide range of malicious activities that severely affect WordPress sites and their users:
- Create unauthorized administrator accounts: Using functions like
wp_insert_user(), attackers can add admin users to maintain persistent control - Install malicious backdoors: Backdoors allow attackers to regain access even after patches or cleanup
- Upload malware and malicious plugins: Infect visitors’ browsers or steal sensitive data
- Steal sensitive data: Extract customer information, payment details, and confidential business data from the WordPress database
- Deface websites: Replace legitimate content with spam, phishing pages, or malicious redirects
- Use compromised servers for attacks: Launch distributed denial-of-service (DDoS) attacks, send spam, or mine cryptocurrency
- Inject malicious code: Modify site files to redirect visitors or serve malware
The consequences extend beyond technical compromise. Cleanup costs for affected WordPress sites typically range from €450 to €2,500, with downtime lasting 3–7 days and reputation damage that can take months to recover[2][5].
Identifying Indicators of Compromise (IoCs) in the Sneeit Framework Plugin
If your WordPress site was running a vulnerable version of the Sneeit Framework plugin during the active exploitation period, it is crucial to check for signs of compromise:
- Unknown administrator accounts: Inspect WordPress Users for unfamiliar admin accounts
- Modified plugin files: Check for unexpected changes in
wp-content/plugins/sneeit-framework/directory timestamps or file contents - Suspicious PHP files: Look for files like
finderdata.txtorgoodfinderdata.txt, generated by attacker shell-finder tools - Malicious AJAX activity: Review server logs for suspicious AJAX POST requests to
wp-admin/admin-ajax.phpfrom known attacking IPs (e.g., 185.125.50.59, 182.8.226.51, 89.187.175.80, 87.121.84.52) - Unexpected files in root directory: Identify unfamiliar files in your WordPress root directory
- Database modifications: Look for unauthorized changes in WordPress database tables, especially users and options
