CVE-2025-15662 Overview
CVE-2025-15662 affects the Printcart Web to Print Product Designer for WooCommerce WordPress plugin in versions before 2.5.3. The plugin accepts a user-supplied URL and fetches it server-side without validating the target or enforcing authorization. Unauthenticated attackers can abuse this behavior to read arbitrary local files, including configuration files containing database credentials and secret keys, and to issue server-side requests to internal resources. The flaw is categorized as Server-Side Request Forgery [CWE-918].
Critical Impact
Unauthenticated attackers can exfiltrate sensitive configuration data and pivot to internal network services through the vulnerable WordPress site.
Affected Products
- Printcart Web to Print Product Designer for WooCommerce WordPress plugin
- All versions prior to 2.5.3
- WordPress sites running WooCommerce with the affected plugin enabled

Technical Details for CVE-2025-15662
Vulnerability Analysis
The plugin exposes a request-handling endpoint that retrieves a resource specified by a URL parameter supplied in the HTTP request. The endpoint performs the fetch on the server without validating the URL scheme, host, or destination, and without confirming that the caller is authenticated or authorized. As a result, an attacker can direct the server to fetch file:// URIs and internal HTTP endpoints. This behavior maps directly to Server-Side Request Forgery [CWE-918]. According to WPScan, exploitation returns the fetched content to the attacker, converting the SSRF primitive into an arbitrary file read against the WordPress host.
Root Cause
The root cause is missing input validation combined with missing authorization enforcement in the URL-fetch handler. The plugin trusts user input as the fetch target and does not restrict allowed schemes, resolve hostnames against a deny list, or verify the request originates from a permitted role. Version 2.5.3 introduces the required restrictions.
Attack Vector
Exploitation requires only network access to the WordPress site. An attacker sends a crafted HTTP request to the vulnerable endpoint with a URL parameter pointing to a local file such as /etc/passwd or wp-config.php, or to an internal service address such as http://127.0.0.1 or a cloud metadata endpoint. The server returns the fetched content, exposing credentials, API keys, and internal service responses. No authentication or user interaction is required.
No verified public proof-of-concept code has been published. Technical details are described in the WPScan Vulnerability Report.
Detection Methods for CVE-2025-15662
Indicators of Compromise
- Unauthenticated HTTP requests to Printcart plugin endpoints containing URL parameters with file://, http://127.0.0.1, http://localhost, or cloud metadata IPs such as 169.254.169.254
- Web server access logs showing responses returning contents of wp-config.php or similar sensitive files
- Outbound requests from the WordPress host to internal-only network ranges initiated by the PHP worker process
Detection Strategies
- Inspect WordPress access logs for requests targeting Printcart plugin paths that include URL-valued query parameters or POST bodies
- Alert on HTTP responses from the WordPress host that contain strings such as DB_PASSWORD, AUTH_KEY, or SECURE_AUTH_KEY
- Correlate unauthenticated requests to plugin endpoints with subsequent outbound connections from the web server to RFC1918 or link-local addresses
Monitoring Recommendations
- Enable and centralize WordPress and web server logs for pattern-based analysis
- Monitor egress traffic from web servers and flag connections to internal services that should not receive traffic from the DMZ
- Track plugin version inventory across managed WordPress sites and alert when versions below 2.5.3 are present
How to Mitigate CVE-2025-15662
Immediate Actions Required
- Upgrade the Printcart Web to Print Product Designer for WooCommerce plugin to version 2.5.3 or later
- Rotate any credentials, API keys, and WordPress secret keys stored in wp-config.php if exploitation is suspected
- Review web server and application logs for indicators of SSRF or local file read attempts
Patch Information
The vendor addressed the vulnerability in Printcart Web to Print Product Designer for WooCommerce version 2.5.3. The patch adds URL validation and enforces an authorization check on the server-side fetch handler. Refer to the WPScan Vulnerability Report for advisory details.
Workarounds
- Disable or remove the Printcart plugin until the site can be upgraded to 2.5.3
- Restrict access to plugin endpoints at the web application firewall by blocking requests containing file:// or internal IP addresses in URL parameters
- Apply egress filtering on the WordPress host to prevent connections from the PHP process to internal networks and cloud metadata services
# Example WAF rule concept: block SSRF payloads targeting Printcart endpoints
SecRule REQUEST_URI "@contains /wp-content/plugins/printcart" \
"chain,deny,status:403,id:1015662,msg:'Block SSRF attempt against Printcart plugin'"
SecRule ARGS "@rx (?i)(file://|127\.0\.0\.1|localhost|169\.254\.169\.254)" \
"t:none,t:urlDecodeUni"
