CVE-2026-20975

Local file access via missing permission check

Published Jan 9, 2026 · Updated Jan 9, 2026

Improper permission handling in Samsung Cloud before 5.6.11 allows local attackers to access specific files through arbitrary paths. Samsung has not identified the affected component or disclosed which operation omits the required permission check for an attacker-chosen path. Exploitation requires local device access and an additional attack condition; published effects are confined to specific-file access and limited availability loss.
