Summary

Details

Buildx is a Docker CLI plugin that extends build capabilities using BuildKit. Cache backends support credentials by setting secrets directly as attribute values in cache-to/cache-from configuration. When supplied as user input, these secure values may be inadvertently captured in OpenTelemetry traces as part of the arguments and flags for the traced CLI command. OpenTelemetry traces are also saved in BuildKit daemon's history records. This vulnerability does not impact secrets passed to the Github cache backend via environment variables or registry authentication.
