CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in S3 Bubble Amazon S3 HTML5 Video with Adverts <= 0.7 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 S3 Bubble Amazon S3 HTML5 Video with Adverts the fix is 0.8: builds <= 0.7 are affected, anything from 0.8 onward is not.
Remediation
Update to version 0.8, or a newer patched version
