Description

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.

Executive Summary

This vulnerability exists in PubNet versions prior to 1.1.3, where the /api/storage/upload endpoint allows unauthenticated users to upload packages by specifying arbitrary author-id values. This flaw enables attackers to spoof identities, escalate privileges, and conduct supply chain attacks by impersonating any user.

Impact Analysis
