Official Description
Path traversal in Smart Switch prior to version 3.7.69.15 allows adjacent attackers to overwrite arbitrary files with Smart Switch privilege.
Technical Analysis
CVE-2026-21005 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation does not require any privileges, though user interaction (P) is needed, which slightly reduces the risk of mass automated attacks.
