CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in PayPal Currency Converter BASIC for WooCommerce <= 1.3 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 PayPal Currency Converter BASIC for WooCommerce the fix is 1.4: builds <= 1.3 are affected, anything from 1.4 onward is not.
Remediation
Update to version 1.4, or a newer patched version
