A hardcoded credential vulnerability exists in the firmware of multiple TP-Link routers (TL-WR845N v4, TL-WR850N v3, Archer C20 v6 & Archer MR200 v5). Authentication-related credential material is embedded within a password file in the firmware image and may be recovered through firmware analysis. Successful exploitation could result in unauthorized access to privileged functions on affected devices.
