CVE-2026-50529Public exploitNetwork attack vector

Protected-share access via premature link-token issuance

Published Jul 7, 2026 · Updated Jul 7, 2026

Incorrect authorization in FIT2CLOUD DataEase before 2.10.24 allows remote attackers to access protected shares via a known share UUID. XpackShareManage.proxyInfo generates and adds X-DE-LINK-TOKEN to the response before checking the supplied share password or ticket. Possession of a protected share UUID is required; missing or invalid credentials still yield a token accepted by subsequent share-related API calls.
