Summary

PubNet is a self-hosted Dart & Flutter package service. Prior to version 1.1.3, the /api/storage/upload endpoint in PubNet allows unauthenticated users to upload packages as any user by providing arbitrary author-id values. This enables identity spoofing, privilege escalation, and supply chain attacks. This issue has been patched in version 1.1.3.

Risk Assessment

Risk of identity spoofing, privilege escalation, and supply chain attacks, potentially leading to package integrity compromise.

Recommendation

Immediately update PubNet to version 1.1.3 or later and enforce authentication for the upload endpoint.
