CVE-2026-90621 Details
Description
A vulnerability was identified in ipa-lab HackingBuddyGPT up to 0.5.0. This affects the function ssh_run_command of the file src/hackingBuddyGPT/extensions/ssh_run_command.py. Such manipulation leads to os command injection. The attack can be launched remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
A command injection vulnerability has been identified in ipa-lab HackingBuddyGPT versions through 0.5.0. The issue resides in the SSH command execution feature, specifically within the 'ssh_run_command' function of 'src/hackingBuddyGPT/extensions/ssh_run_command.py'. This vulnerability allows for remote OS command injection, with the potential for exploitation on the operator's local workstation via an active 'tmux' session.
Users are advised to sanitize output from target systems before it is processed by the LLM, ensuring that any potentially harmful instructions are stripped or escaped. Additionally, commands generated by the LLM should be executed in a controlled, sandboxed environment rather than directly on the operator's workstation. Implementing a validation layer that checks commands against an allowlist before execution can also help mitigate this vulnerability.
