CVE-2025-32671: Print Science Designer Path Traversal

CVE-2025-32671 is a path traversal vulnerability in Print Science Designer by John Weissberg that allows unauthorized file access. This article covers the technical details, affected versions up to 1.3.155, and mitigation.

Updated: May 15, 2026

CVE-2025-32671 Overview

CVE-2025-32671 is a path traversal vulnerability [CWE-22] in the Print Science Designer WordPress plugin (print-science-designer) developed by John Weissberg. The flaw affects all versions up to and including 1.3.155. Unauthenticated attackers can exploit it over the network to read arbitrary files from the underlying server.

The issue is classified as an arbitrary file download vulnerability. Successful exploitation exposes sensitive files such as wp-config.php, which contains database credentials and WordPress authentication secrets.

Critical Impact

Unauthenticated remote attackers can download arbitrary files from affected WordPress installations, leading to credential disclosure and potential full site compromise.

Affected Products

  • Print Science Designer WordPress plugin versions through 1.3.155
  • WordPress sites with the print-science-designer plugin installed and active
  • Hosting environments where the plugin runs without additional path filtering controls

Discovery Timeline

  • 2026-04-23 - Last updated in NVD database

Technical Details for CVE-2025-32671

Vulnerability Analysis

The vulnerability stems from improper limitation of a pathname to a restricted directory within the Print Science Designer plugin. The plugin accepts a user-controlled file path parameter and passes it to a file read or download routine without canonicalizing or validating the input against an allowlist.

Attackers supply traversal sequences such as ../ to escape the intended directory. The plugin then resolves the path and returns the file contents to the requester. No authentication is required, and the attack requires no user interaction.

The scope is limited to confidentiality. The vulnerability does not provide direct write or execution primitives, but disclosed credentials and secrets frequently lead to follow-on compromise of the WordPress admin account and the database.

Root Cause

The root cause is missing input sanitization on a file path parameter handled by the plugin. The code does not reject directory traversal sequences and does not constrain the resolved path to a trusted base directory. WordPress plugins typically should use functions like realpath() combined with prefix checks, or wp_check_filetype_and_ext() with hardcoded directories.

Attack Vector

The attack vector is network-based over HTTP or HTTPS. An attacker sends a crafted request to the vulnerable plugin endpoint with a manipulated file parameter pointing at a sensitive location on the filesystem. Common targets include wp-config.php, /etc/passwd, backup archives, and log files containing session tokens.

The vulnerability mechanism is described in the Patchstack Vulnerability Report. No verified public proof-of-concept code is available at the time of writing.

Detection Methods for CVE-2025-32671

Indicators of Compromise

  • HTTP requests to Print Science Designer plugin endpoints containing ../, ..%2f, or URL-encoded traversal sequences in query parameters
  • Outbound responses from WordPress containing contents of wp-config.php, .htaccess, or other sensitive files
  • Unusual access patterns to plugin files under /wp-content/plugins/print-science-designer/ from a single source IP
  • Subsequent authenticated admin logins from IP addresses that previously probed plugin endpoints

Detection Strategies

  • Inspect web server access logs for query string parameters containing path traversal patterns targeting the plugin path
  • Deploy a web application firewall rule that blocks requests containing ../ sequences directed at /wp-content/plugins/print-science-designer/
  • Correlate file download responses larger than expected with requests to plugin endpoints
  • Hunt for known sensitive filenames such as wp-config.php appearing in HTTP response bodies

Monitoring Recommendations

  • Forward WordPress and reverse proxy logs to a centralized analytics platform for retroactive hunting
  • Alert on any HTTP 200 response from the plugin endpoint where the request contains traversal characters
  • Monitor for new administrator accounts or modified wp_users entries following suspicious plugin traffic
  • Track file integrity on wp-config.php and other configuration files for unexpected access timestamps

How to Mitigate CVE-2025-32671

Immediate Actions Required

  • Disable or remove the Print Science Designer plugin until a patched version is confirmed installed
  • Rotate WordPress database credentials, secret keys, and salts defined in wp-config.php
  • Audit administrator accounts and force password resets for all privileged users
  • Review web server logs from the public disclosure date forward for exploitation attempts

Patch Information

The vulnerability affects Print Science Designer versions through 1.3.155. Refer to the Patchstack advisory for vendor patch availability and update the plugin to the latest version available from the WordPress plugin repository.

Workarounds

  • Block requests containing ../ or encoded variants at the WAF or reverse proxy layer before they reach WordPress
  • Restrict filesystem permissions so the web server user cannot read files outside the WordPress webroot
  • Move wp-config.php one directory above the WordPress installation root where supported
  • Deactivate the plugin via WP-CLI using wp plugin deactivate print-science-designer until remediation is confirmed
bash
# Configuration example
# Deactivate the vulnerable plugin via WP-CLI
wp plugin deactivate print-science-designer

# Example nginx rule to block traversal attempts against the plugin
location ~* /wp-content/plugins/print-science-designer/ {
    if ($args ~* "\.\./|\.\.%2f|%2e%2e") {
        return 403;
    }
}
