What is CVE-2026-51870?

The DeepTutor application (version 1.4.0) contains a vulnerability that allows unauthorized command execution. This issue arises from insufficient validation in the /tutorbot/agent/tools/shell.py:ExecTool.execute function, which can be exploited by an attacker to execute arbitrary commands on the server. Proper safeguards should be implemented to mitigate this risk.
