CVE-2025-48081 Overview
CVE-2025-48081 is a path traversal vulnerability affecting the Printeers Print & Ship plugin for WordPress. The flaw exists in versions up to and including 1.17.0 and is tracked under CWE-35: Path Traversal: '.../...//'. Attackers can exploit improperly sanitized path input to access files outside the intended directory. The vulnerability is exploitable over the network without authentication or user interaction. Successful exploitation leads to limited integrity impact but no direct confidentiality or availability loss according to the published CVSS metrics.
Critical Impact
Unauthenticated remote attackers can traverse directories using crafted .../...// sequences to access files outside the plugin's intended scope.
Affected Products
- Printeers Print & Ship WordPress plugin (also known as invition-print-ship)
- All versions from initial release through 1.17.0
- WordPress sites with the vulnerable plugin installed and activated

Technical Details for CVE-2025-48081
Vulnerability Analysis
The vulnerability is a directory traversal flaw classified under CWE-35. The Printeers Print & Ship plugin fails to properly neutralize path traversal sequences of the form .../...// in user-supplied input. This specific pattern bypasses naive sanitization routines that only strip single ../ sequences. When the filter removes ../, the residual characters recombine to form a valid traversal sequence.
The attack vector is network-based and requires no authentication or user interaction. Impact is limited to integrity according to the CVSS metrics, indicating attackers can influence file paths handled by the plugin but cannot directly read arbitrary confidential data or crash the service through this flaw alone.
The EPSS score is 0.306% at the 22.4 percentile, indicating relatively low predicted exploitation activity. No public proof-of-concept has been observed, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Root Cause
The plugin's file-handling logic performs insufficient input validation on path parameters. Filters that strip ../ substrings without recursive or canonical path resolution allow the .../...// bypass. After a single-pass replacement, the remaining characters form the classic ../ traversal sequence, permitting access outside the intended directory root.
Attack Vector
An unauthenticated attacker sends an HTTP request to the vulnerable plugin endpoint containing a crafted path parameter with .../...// sequences. The plugin resolves the path after incomplete sanitization, granting access to files or resources outside the plugin's intended working directory. Refer to the Patchstack WordPress Vulnerability Report for technical details.
Detection Methods for CVE-2025-48081
Indicators of Compromise
- HTTP requests to Printeers Print & Ship endpoints containing .../...//, ....//, or URL-encoded variants such as %2e%2e%2f
- Web server access logs showing requests with unusual path parameters targeting wp-content/plugins/invition-print-ship/
- Unexpected file reads from directories outside the plugin's installation path
Detection Strategies
- Inspect WordPress and web server access logs for path traversal patterns targeting the plugin's endpoints
- Deploy a Web Application Firewall (WAF) rule set that identifies path traversal signatures including obfuscated variants
- Correlate anomalous file access patterns on the WordPress host with inbound HTTP requests to the plugin
Monitoring Recommendations
- Enable verbose HTTP request logging on the WordPress front-end web server
- Monitor filesystem access on wp-content/ and adjacent directories for unexpected read operations
- Alert on repeated 4xx responses to plugin endpoints, which may indicate reconnaissance
How to Mitigate CVE-2025-48081
Immediate Actions Required
- Identify all WordPress installations running the Printeers Print & Ship plugin at version 1.17.0 or earlier
- Deactivate the plugin until an updated version resolving the traversal flaw is confirmed available
- Review web server logs for prior exploitation attempts using the .../...// pattern
Patch Information
Consult the Patchstack advisory for the latest fixed release from the vendor. Upgrade to a version later than 1.17.0 once published by Printeers. Verify the update through the WordPress plugin dashboard or by inspecting the plugin's readme.txt version header.
Workarounds
- Deploy a WAF rule blocking requests containing .../...//, ....//, and URL-encoded traversal sequences targeting the plugin path
- Restrict access to the plugin's endpoints via IP allowlisting where operationally feasible
- Apply filesystem-level permissions to limit the WordPress process's read access to only required directories
