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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
