The exploit path involves creating a malicious user account via the web interface, so an attacker would need valid local credentials or administrative access to the machine."}}}}, "created": "2026-03-12T09:57:17.898507+00:00", "updated": "2026-03-20T15:29:52.536462+00:00", "vendors": ["sharing-file", "sharing-file$PRODUCT$easy_file_sharing_web_server"]}
