## Impact

Using the `--allow-untrusted` option with the APK package manager (`apk`) in Dockerfiles is a significant security risk. This flag tells APK to skip the signature verification process for packages, allowing the installation of packages that have not been cryptographically signed.

By bypassing the signature verification, you expose your Docker containers to potential threats like tampered packages, which can lead to the inclusion of malicious code or vulnerable software versions in your container images.

## How to Fix

## \[source,go]

* RUN apk add --no-cache --allow-untrusted somepackage
* RUN apk add --no-cache somepackage

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/compute/appsec2-docker-7.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
