Root Cause Analysis

The key vulnerability manifests in MediaManager's save() method where:

Pre-patch code accepted non-string 'filename' values without validation (like arrays)
Missing is_string() checks allowed exceptional conditions to propagate
XSS payloads in filename weren't properly sanitized before the xss_clean() addition
Tests added in the patch (testSaveMediaArrayInFilename) directly validate this failure scenario
CWE-755 is addressed by added type checks, and CWE-544 by standardizing error returns (return false) for invalid inputs
