CVE-2026-25397 is a path traversal vulnerability identified in the Snowray Software File Uploader for WooCommerce plugin, specifically in versions up to and including 1.0.4. The vulnerability arises from improper sanitization of file path inputs, allowing attackers to use crafted sequences such as '.../...//' to traverse directories beyond the intended upload folder. This can lead to unauthorized access to sensitive files on the server or the ability to upload malicious files outside the designated directory, potentially facilitating remote code execution or data leakage. The flaw is rooted in the plugin's failure to adequately validate and normalize file paths before processing uploads. Although no public exploits have been reported yet, the nature of path traversal vulnerabilities makes them attractive targets for attackers, especially in e-commerce environments where file uploads are common. The vulnerability was reserved in early February 2026 and published in late March 2026, with no CVSS score assigned. The affected product is widely used in WooCommerce-based online stores, which are prevalent globally, increasing the potential attack surface. The lack of a patch link suggests that a fix may still be pending or in development, emphasizing the need for immediate mitigation measures.

The exploitation of this path traversal vulnerability can have severe consequences for organizations running WooCommerce stores with the vulnerable plugin. Attackers could access sensitive configuration files, customer data, or other critical information stored on the server, leading to confidentiality breaches. Additionally, by uploading malicious scripts outside the intended directory, attackers might achieve remote code execution, compromising the entire web server and potentially the underlying network. This can result in data loss, defacement, service disruption, and reputational damage. Given WooCommerce's extensive use in global e-commerce, the impact could be widespread, affecting both small and large online retailers. The vulnerability also poses risks to compliance with data protection regulations if customer data is exposed. The absence of known exploits currently provides a window for organizations to remediate before active attacks emerge, but the ease of exploitation and potential damage elevate the threat level significantly.

Organizations should immediately audit their WooCommerce installations to identify the presence of the Snowray Software File Uploader plugin and its version. If version 1.0.4 or earlier is in use, they should seek updates or patches from the vendor as a priority. In the absence of an official patch, temporary mitigations include implementing strict input validation and sanitization on file upload paths to prevent traversal sequences like '.../...//'. Web application firewalls (WAFs) can be configured to detect and block suspicious path traversal patterns in HTTP requests. Restricting file system permissions for the web server user to limit access outside designated upload directories can reduce the impact of exploitation. Monitoring logs for unusual file access or upload activity can help detect attempted exploitation. Additionally, disabling or removing the vulnerable plugin until a fix is available is advisable. Organizations should also review their incident response plans to prepare for potential exploitation scenarios.
