Arbitrary file write via Zip Slip path traversal in TP-Link's WebUI ISP Upgrade functionality affects three LTE router models - TL-MR6400 v5.3, Archer MR600 v2, and Archer MR200 v7. An authenticated administrator on the adjacent network can upload a crafted archive containing directory traversal sequences (e.g., '../../') to overwrite arbitrary files on the underlying system, compromising integrity and potentially availability. No public exploit code or CISA KEV listing has been identified; vendor-released patches are available as of mid-2026.
