CVE-2026-121864nanobot-ai >= 0.2.1,

NVD

Vulnerability Summary

Impact When sandboxed `exec` is enabled, an attacker who can induce the agent to create an executable in the workspace and select it as the shell can cause that executable to run outside the sandbox, with the nanobot process's operating-system permissions. This does not imply root access. The reported runtime validation used Linux bubblewrap; exploitation through chat also depends on the agent carrying out the required tool actions. Patches Upgrade `nanobot-ai` to 0.4.1 or later using the existing installation method, and restart the gateway. The fix launches the sandbox before the selected shell.
