A flaw was found in Nextcloud Server. A malicious user with access to a file share could exploit this vulnerability by using the share token to directly access the chunking upload process. This allows the attacker to view temporary part files during ongoing uploads, leading to information disclosure. This issue could expose sensitive data being uploaded by other users.
