Upgrade renovate to version 44.14.7 or higher.
Overview
renovate is a dependency updater.
Affected versions of this package are vulnerable to Command Injection in the Mix manager's Hex registry authentication, which interpolates the organization value derived from the dependency name into the mix hex.organization auth invocation without escaping. An attacker can execute commands as the Renovate user, or append their own arguments to that authentication call, by placing a dependency name such as private_package:evil --key leaked_or_arbitrary in the manifest, which expands to mix hex.organization auth evil --key leaked_or_arbitrary --key secret_token. This requires a self-hosted Renovate with binarySource=docker, private Mix dependencies configured, and a dependency name that would not be valid for Mix.
