CVE-2026-10873Public exploitNetwork attack vector

Authenticated command execution via unsanitized rstats_path

Published Jun 4, 2026 · Updated Jun 4, 2026

OS command injection in the Web UI of Shibby Tomato 1.28.0000 allows remote authenticated users to execute arbitrary commands. The /bin/rstats rstats_path handler places an administrator-controlled NVRAM value into an operating-system command without neutralizing shell metacharacters. Administrative access to the router Web UI is required, and successful exploitation runs commands with the firmware service's privileges.
