CVE-2025-60227: WP Pipes Path Traversal Vulnerability

CVE-2025-60227 Overview

CVE-2025-60227 is a path traversal vulnerability affecting the ThimPress WP Pipes WordPress plugin. This security flaw stems from improper limitation of a pathname to a restricted directory (CWE-22), allowing attackers to traverse directory paths and potentially access or delete arbitrary files on the affected WordPress installation.

Critical Impact

This vulnerability enables unauthenticated remote attackers to exploit path traversal sequences to perform arbitrary file deletion, potentially leading to complete denial of service by removing critical WordPress files.

Affected Products

• ThimPress WP Pipes plugin versions up to and including 1.4.3
• WordPress installations running vulnerable WP Pipes versions
• Any web application utilizing the affected wp-pipes component

Technical Details for CVE-2025-60227

Vulnerability Analysis

The vulnerability exists within the WP Pipes plugin's file handling mechanisms. Due to insufficient validation of user-supplied file paths, the plugin fails to properly sanitize directory traversal sequences such as ../ before processing file operations. This improper pathname limitation allows attackers to escape the intended directory restrictions and target files outside the plugin's designated scope.

The attack can be executed remotely over the network without requiring any authentication or user interaction. When exploited, attackers can achieve arbitrary file deletion, which primarily impacts system availability. Critical WordPress files such as wp-config.php or core installation files could be targeted, effectively rendering the WordPress site non-functional.

Root Cause

The root cause of CVE-2025-60227 is the failure to implement proper input validation and sanitization for file path parameters within the WP Pipes plugin. The vulnerable code does not adequately filter or reject path traversal sequences (../, ..\\, or URL-encoded variants) before using user-supplied input in file system operations. This allows malicious actors to construct requests that reference files outside the intended directory boundaries.

Attack Vector

The attack vector for this vulnerability is network-based, meaning exploitation can occur remotely without requiring local access to the target system. An unauthenticated attacker can craft malicious HTTP requests containing path traversal sequences targeting the vulnerable WP Pipes endpoints. The attack requires no privileges and no user interaction, making it particularly dangerous for publicly accessible WordPress installations.

The exploitation mechanism involves injecting directory traversal patterns into parameters that are subsequently used in file deletion operations. For example, an attacker might manipulate a file path parameter to include sequences like ../../../wp-config.php to target critical WordPress configuration files outside the plugin's directory.

Detection Methods for CVE-2025-60227

Indicators of Compromise

• HTTP requests to WP Pipes plugin endpoints containing ../ or encoded path traversal sequences (%2e%2e%2f, %2e%2e/)
• Missing critical WordPress files such as wp-config.php, .htaccess, or core plugin/theme files
• Web server access logs showing repeated requests to /wp-content/plugins/wp-pipes/ with unusual path parameters
• Unexpected WordPress errors indicating missing configuration or core files

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block requests containing path traversal patterns targeting WordPress plugin endpoints
• Monitor file integrity of critical WordPress files using file integrity monitoring (FIM) solutions
• Configure intrusion detection systems (IDS) to alert on HTTP requests with directory traversal indicators
• Review web server access logs for suspicious activity targeting the WP Pipes plugin directory

Monitoring Recommendations

• Enable detailed logging for all requests to the /wp-content/plugins/wp-pipes/ directory
• Set up real-time alerts for file deletion events within the WordPress installation directory
• Implement automated scanning for path traversal attempts in web application logs
• Monitor WordPress site health and availability to quickly detect potential denial of service conditions

How to Mitigate CVE-2025-60227

Immediate Actions Required

• Immediately deactivate and delete the WP Pipes plugin if not essential for site operations
• Update the WP Pipes plugin to a patched version when available from ThimPress
• Implement WAF rules to block path traversal attempts targeting the plugin
• Backup all critical WordPress files and database before taking remediation actions

Patch Information

Organizations using ThimPress WP Pipes should check for plugin updates beyond version 1.4.3. Visit the WordPress plugin repository or the ThimPress website for the latest security patches. Until a patch is available, consider the workarounds listed below to reduce exposure.

For the official vulnerability report and remediation guidance, see the Patchstack advisory.

Workarounds

• Disable the WP Pipes plugin entirely until a patched version is released
• Restrict access to the plugin's endpoints using .htaccess rules or web server configuration
• Implement additional input validation at the web server level using ModSecurity or similar WAF solutions
• Limit file system permissions to prevent the web server user from deleting critical files

# Example .htaccess rule to block access to WP Pipes plugin
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^wp-content/plugins/wp-pipes/.*$ - [F,L]
</IfModule>
