CVE-2026-26213

Root command execution via unsanitized parameter names

Published Mar 26, 2026 · Updated Mar 26, 2026

OS command injection in Thingino Firmware through firmware-2026-03-16 allows remote attackers to execute root commands through the WiFi portal. The api.cgi parse_query() and parse_post() functions pass unsanitized HTTP parameter names to eval, causing the shell to interpret injected syntax. Unauthenticated access to the camera's captive-portal network is sufficient; successful exploitation permits password resets, SSH key changes, and persistent device control.
