What it detects
Dockerfile doesn't drop privileges (no USER directive in file): an infrastructure as code check run by the textscan analyzer.
Evidence
The matching source path, line, and bounded code observation produced by the native rule.
Remediation
Add `USER <non-root>` after package installs. Containers running as UID 0 escalate easily into the host on misconfigured runtimes.
Limitations
This check is limited to the applicability and evidence delivered by textscan. Review the evidence in context; a match is a finding input, while confidence and policy determine its disposition.
