CVE-2026-6250

An authenticated format string vulnerability exists in the ONVIF service of Tapo C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as a format string, which can be used to manipulate stack memory, including control flow data such as return addresses. A remote authenticated attacker may redirect execution flow to existing internal functions, triggering an unauthorized factory reset, leading to loss of configuration, deletion of stored credentials and service disruption.
