Vulnerability Overview

Absolute path traversal vulnerability in include/user/download.php in the Swim Team plugin 1.44.10777 for WordPress allows remote attackers to read arbitrary files via a full pathname in the file parameter.

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 Swim Team <= 1.44.1077 takes a caller who can reach the endpoint. 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 Swim Team the fix is 1.45.1085: builds <= 1.44.1077 are affected, anything from 1.45.1085 onward is not.

Remediation

Update to version 1.45.1085, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Swim Team: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Swim Team 1.45.1085 closes this, and updating the plugin is the step that ends it.
