Root Cause Analysis

The vulnerability stems from writing files using unvalidated ObjectName parameters. The key evidence is:

The original code used path.Join() which doesn't prevent directory traversal when combined with user input
The patch adds validateFilePath() to check for '..' segments
The function signature shows direct handling of user-controlled file paths
The test file addition confirms path validation was a new security control While the validation function itself is new, the primary vulnerable execution path flows through MountSecretsStoreObjectContent which was modified to add security checks.
