CVE-2025-32671 Overview
CVE-2025-32671 is a Path Traversal vulnerability (CWE-22) affecting the Print Science Designer WordPress plugin developed by John Weissberg. This vulnerability allows attackers to traverse directory paths and access files outside of the intended restricted directory, potentially enabling arbitrary file download capabilities on affected WordPress installations.
Critical Impact
Attackers can exploit this path traversal flaw to download sensitive files from the web server, including WordPress configuration files containing database credentials, private keys, and other confidential data stored on the system.
Affected Products
- Print Science Designer WordPress Plugin versions through 1.3.155
- WordPress installations running the vulnerable plugin versions
- Web servers hosting affected WordPress sites

Technical Details for CVE-2025-32671
Vulnerability Analysis
This path traversal vulnerability exists in the Print Science Designer WordPress plugin due to improper limitation of pathnames to a restricted directory. The plugin fails to adequately sanitize user-supplied input when handling file path parameters, allowing malicious actors to include directory traversal sequences (such as ../) in requests. This enables attackers to escape the intended directory constraints and access arbitrary files on the underlying web server.
The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), which represents a common class of security flaws where applications accept external input to construct file paths without proper validation. According to the PatchStack Vulnerability Report, this specific implementation allows arbitrary file download, significantly increasing the risk of sensitive data exposure.
Root Cause
The root cause of this vulnerability stems from insufficient input validation and sanitization within the Print Science Designer plugin. When processing file path parameters, the plugin does not properly filter or reject directory traversal sequences. This allows attackers to manipulate the file path to navigate outside of the web application's document root and access sensitive system files.
The vulnerable code path fails to implement proper canonicalization of file paths and does not restrict access to a predetermined safe directory. Without these safeguards, any user input containing traversal patterns can be leveraged to read arbitrary files from the server's file system.
Attack Vector
An attacker can exploit this vulnerability by crafting malicious HTTP requests that include path traversal sequences in file-related parameters. By injecting sequences like ../ or encoded variants (%2e%2e%2f), the attacker can navigate up the directory tree and specify paths to sensitive files.
Typical targets for this type of attack on WordPress installations include:
- wp-config.php - Contains database credentials and authentication keys
- /etc/passwd - System user information on Linux servers
- Log files containing sensitive application data
- Backup files that may contain database dumps
The attacker does not require authentication to exploit this vulnerability, making it particularly dangerous for publicly accessible WordPress sites running the affected plugin versions.
Detection Methods for CVE-2025-32671
Indicators of Compromise
- Unusual HTTP requests containing directory traversal sequences (../, ..%2f, %2e%2e/) targeting the Print Science Designer plugin endpoints
- Access logs showing requests for sensitive files like wp-config.php through non-standard paths
- Evidence of files being accessed from outside the WordPress web root directory
- Unexpected download activity for configuration files or system files
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block requests containing path traversal patterns
- Monitor access logs for suspicious requests targeting the print-science-designer plugin directory with traversal sequences
- Configure intrusion detection systems (IDS) to alert on attempts to access sensitive system files via web requests
- Utilize SentinelOne's behavioral detection capabilities to identify unusual file access patterns on web servers
Monitoring Recommendations
- Enable detailed logging for all HTTP requests to WordPress installations
- Set up alerts for access attempts to sensitive configuration files from web server processes
- Monitor for anomalous file read operations originating from the web server user account
- Implement file integrity monitoring on critical WordPress configuration files
How to Mitigate CVE-2025-32671
Immediate Actions Required
- Update the Print Science Designer plugin to a patched version as soon as one becomes available from the vendor
- Consider temporarily deactivating the Print Science Designer plugin until a security patch is released
- Implement WAF rules to block path traversal attempts targeting the affected plugin
- Review server access logs for signs of exploitation attempts
- Rotate credentials stored in wp-config.php if potential compromise is suspected
Patch Information
Users should monitor the official WordPress plugin repository and vendor communications for security updates to the Print Science Designer plugin. Check the PatchStack Vulnerability Report for the latest remediation guidance and patch availability.
Until an official patch is available, administrators should implement compensating controls to reduce the risk of exploitation.
Workarounds
- Disable or uninstall the Print Science Designer plugin if it is not critical to site operations
- Implement strict WAF rules to block requests containing path traversal patterns (../, ..\\, encoded variants)
- Restrict file system permissions to limit the web server user's read access to only necessary directories
- Use .htaccess or server configuration rules to deny direct access to sensitive files from web requests
- Consider implementing a reverse proxy with input validation to filter malicious requests
# Apache .htaccess configuration to block path traversal attempts
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.) [NC,OR]
RewriteCond %{REQUEST_URI} (\.\./|\.\.) [NC]
RewriteRule .* - [F,L]
</IfModule>
# Block direct access to sensitive files
<FilesMatch "^(wp-config\.php|\.htaccess|readme\.html|license\.txt)$">
Require all denied
</FilesMatch>
