Description

A vulnerability was identified in eyal-gor p_69_branch_monkey_mcp up to 69bc71874ce40050ef45fde5a435855f18af3373. The affected element is an unknown function of the file branch_monkey_mcp/bridge_and_local_actions/routes/advanced.py of the component Preview Endpoint. Such manipulation of the argument dev_script leads to os command injection. The attack can be launched remotely. The exploit is publicly available and might be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.
