## Affected

- AtalayaLabs OxiCloud: from 0.9.1, through 0.9.3

## Description

OxiCloud 0.9.1 through 0.9.3 contains an incorrect authorization vulnerability that allows anonymous visitors to keep share access after password protection is added. Attackers holding an existing oxi_shares share-ring cookie can request content via GET /api/files/{id} to read shared files or folder contents despite the new password.
