CVE-2026-21000

Local privileged file creation

Published Mar 16, 2026 · Updated Mar 16, 2026

Improper access control in Samsung Galaxy Store before 4.6.03.8 allows local users to create files with Galaxy Store privileges. NVD maps the flaw to path traversal, but Samsung has not disclosed the affected component or the file-path operation that lacks access control. Local access is required; the grounded impact is privileged file creation, with no reported confidentiality or subsequent-system impact.
