CVSS Score
-The vulnerability stems from the decodeFolderFilter method in PortalFolder.py, which was publicly exposed via @security.public and used marshal.loads on unvalidated base64-decoded input. The advisory explicitly identifies this method, and the patch replaced marshal with JSON parsing while adding input length checks. The commit diff confirms the removal of insecure deserialization patterns in this function.
