CVE-2026-111332
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.
Does this matter?
Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.
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.
