Miggo AIRoot Cause Analysis

The vulnerability occurs in the path handling logic of Spring Cloud Config Server's resource serving endpoint. The GenericResourceRepository.findOne method was processing user-supplied paths without adequate validation, allowing directory traversal via encoded path segments. The ResourceController.retrieve method serves as the entry point that passes the unsanitized path parameter to the vulnerable code. The patch adds multiple validation layers (isInvalidPath, processPath, cleanDuplicateSlashes) demonstrating where the original vulnerability existed.
