CVE-2025-65112: Ricardoboss Pubnet

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Ricardoboss Pubnet: before 1.1.4 (fixed in 1.1.4)
