AnalysisAIv1 – Jul 26, 2026

Unauthenticated path traversal in Tenda CH22 router firmware 1.0.0.1 permits remote attackers to manipulate file paths via the /public/ endpoint. Exploitation can result in limited file disclosure, modification, or deletion. Public exploit code is available, but no active exploitation has been confirmed and EPSS indicates low probability of widespread attacks.
