malcontent discovers supply-chain compromises through. context, differential analysis, and YARA. Starting in version 0.10.0 and prior to version 1.20.3, malcontent could be made to expose Docker registry credentials if it scanned a specially crafted OCI image reference. malcontent uses google/go-containerregistry for OCI image pulls, which by default uses the Docker credential keychain. A malicious registry could return a `WWW-Authenticate` header redirecting token authentication to an attacker-controlled endpoint, causing credentials to be sent to that endpoint. Version 1.20.3 fixes the issue by defaulting to anonymous auth for OCI pulls.

    Malcontent could be made to expose Docker registry credentials if it scanned a specially crafted OCI image reference. Malcontent uses [google/go-containerregistry](https://github.com/google/go-containerregistry) for OCI image pulls, which by default uses the Docker credential keychain. A malicious registry could return a `WWW-Authenticate` header redirecting token authentication to an attacker-controlled endpoint, causing credentials to be sent to that endpoint. **Fix:** [Default to anonymous auth for OCI pulls](https://github.com/chainguard-dev/malcontent/commit/538ed00cdc639d687a4bd1e843a2be0428a3b3e7) **Acknowledgements** Thank you to Oleh Konko from [1seal](https://1seal.org/) for discovering and reporting this issue.
