CVE-2025-15662 in Web to Print Product Designer Plugin
Summary
by MITRE • 07/27/2026
The Printcart Web to Print Product Designer for WooCommerce WordPress plugin before 2.5.3 does not restrict a user-supplied URL before fetching it server-side and does not enforce a valid authorization check, allowing unauthenticated attackers to read arbitrary local files (including configuration files containing database credentials and secret keys) and to make server-side requests to internal resources.

The Printcart Web to Print Product Designer for WooCommerce plugin presents a critical server-side request forgery vulnerability that allows unauthenticated attackers to access sensitive local files and make arbitrary internal requests. This flaw exists in versions prior to 2.5.3 and stems from inadequate input validation and authorization mechanisms within the plugin's remote file inclusion functionality. The vulnerability enables attackers to manipulate URL parameters that are processed server-side without proper sanitization or access controls, creating a pathway for unauthorized information disclosure and internal network reconnaissance.
The technical implementation of this vulnerability resides in the plugin's handling of user-supplied URLs during server-side processing operations. When the plugin receives external requests containing URL parameters, it fails to validate these inputs against a whitelist of acceptable domains or implement proper authorization checks before initiating HTTP requests. This design flaw directly aligns with CWE-918, which describes server-side request forgery vulnerabilities where applications fail to properly validate and authorize external resource access. The lack of input validation creates an opportunity for attackers to specify local file paths or internal network addresses that the plugin will attempt to access and retrieve.
The operational impact of this vulnerability extends beyond simple information disclosure to encompass potential system compromise through internal network reconnaissance. Attackers can leverage this flaw to read configuration files containing database credentials, API keys, and cryptographic secrets that are typically stored on the web server filesystem. These credentials could enable further attacks including database access, privilege escalation, or exploitation of other systems within the same network environment. Additionally, the ability to make server-side requests to internal resources provides attackers with a means to map internal networks, identify vulnerable services, and potentially exploit other internal systems that may not be directly exposed to the internet.
This vulnerability represents a significant risk to WordPress installations using the affected plugin version and aligns with ATT&CK technique T1083 (File and Directory Discovery) and T1190 (Exploit Public-Facing Application). The attack surface is particularly concerning because it allows unauthenticated access to what should be protected internal resources, effectively bypassing standard network security controls that typically isolate internal systems from direct internet exposure. Organizations running this plugin version are vulnerable to both passive information gathering and active exploitation attempts that could lead to complete system compromise.
The recommended mitigation strategy involves immediate upgrading to version 2.5.3 or later, which addresses the core input validation and authorization issues. Administrators should also implement additional protective measures including network segmentation, firewall rules restricting access to internal resources, and monitoring for unusual file access patterns. Input validation should be implemented using allowlists of trusted domains rather than blacklisting approaches, and all server-side HTTP requests should require proper authentication tokens or API keys before execution. Regular security audits of plugin installations and implementation of web application firewalls can provide additional defense-in-depth measures against similar vulnerabilities in other components of the WordPress ecosystem.
