Name of the Vulnerable Software and Affected Versions PubNet versions prior to 1.1.3

Description PubNet is a self-hosted Dart & Flutter package service. The /api/storage/upload endpoint 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. The issue allows attackers to forge any author-id, creating a perfect supply chain attack scenario.

Recommendations Versions prior to 1.1.3 should be updated to version 1.1.3 or later.
