Low risk25th percentile - higher than 25% of all known CVEs
Summary
docker-socket-proxy fails to properly gate read endpoints in the /containers Docker API namespace when the CONTAINERS environment variable is set. Attackers can use GET requests to /containers/{id}/archive, /containers/{id}/export, /containers/{id}/logs, and /containers/{id}/top to read arbitrary files and download entire container filesystems as tar archives.
Risk Assessment
The risk includes unauthorized access to sensitive data inside containers and the possibility of full container filesystem exfiltration, which can lead to data leakage and compromise of environment integrity.
Recommendation
It is recommended to immediately update docker-socket-proxy to a version that properly restricts access to the mentioned endpoints, and to review the CONTAINERS environment variable configuration.
