Detection Guidance

This vulnerability involves recursive copying of build context directories into container images, which may expose sensitive information. To detect it, inspect container images for unintended directory inclusions by checking build contexts and Dockerfile commands. Use commands like 'docker history <image>' to review image layers, 'docker inspect <container>' for configuration details, and examine build logs for recursive copy operations.
