DOCKER-030Medium severity-8 points

Build fetches content over cleartext http://

Part of Security, which counts for 30% of the overall score. When this check fires it deducts 8 points from that category, once per scan, no matter how many places it turns up.

What it detects

A RUN downloads with curl/wget over http://, so the response is unauthenticated and can be modified in transit before it lands in the image.

Why it matters

Fetching with curl or wget over http:// pulls content over an unauthenticated, cleartext connection, so anyone on the network path can read or modify the response before it is written into your image. That is a supply-chain tampering risk during the build.

How to fix it

Switch the URL to https:// and keep certificate verification on. Prefer a pinned, versioned artifact and verify it against a checksum after download. If the source has no https endpoint, mirror the artifact somewhere you control that does.
