Last modified

CVE-2026-105810 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. Tapo C320WS V2.0 contains an authenticated stack-based buffer overflow in the local onboarding Wi-Fi configuration path. An authenticated attacker on the adjacent network can submit a crafted request containing an oversized encrypted password field, overwrite stack state, and execute commands with root privileges. Successful exploitation may allow an authenticated adjacent-network attacker to take control of the affected camera, modify camera behavior, access sensitive local configuration, and disrupt device availability.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
