It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The Shared Files – Frontend File Upload Form & Secure File Sharing plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.7.64. This makes it possible for unauthenticated attackers to perform actions on files outside of the originally intended directory.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in Shared Files <= 1.7.64 takes no account at all. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Shared Files the fix is 1.7.65: builds <= 1.7.64 are affected, anything from 1.7.65 onward is not.

Remediation

Update to version 1.7.65, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Shared Files 1.7.65 closes this, and updating the plugin is the step that ends it.
