Adjacent file overwrite via path traversal
Published Mar 16, 2026 · Updated Mar 16, 2026
Path traversal in Samsung Smart Switch before 3.7.69.15 allows adjacent attackers to overwrite arbitrary files with the app's privilege. Samsung has not published the affected component or precise path-handling operation; it states only that the patch adds proper validation logic. Exploitation requires adjacency and passive user interaction, and the overwrite is limited to files writable with Smart Switch privilege.
