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

Reaching this weakness in Chat Widget: Floating Customer Support Button for 30+ Channels, Supporting SMS, Calls, and Chat <= 1.5.4 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 Chat Widget: Floating Customer Support Button for 30+ Channels, Supporting SMS, Calls, and Chat the fix is 1.5.5: builds <= 1.5.4 are affected, anything from 1.5.5 onward is not.

Remediation

Update to version 1.5.5, 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: Chat Widget: Floating Customer Support Button for 30+ Channels, Supporting SMS, Calls, and Chat 1.5.5 closes this, and updating the plugin is the step that ends it.
