Summary
Bash-it 3.2.0 contains a terminal escape sequence injection vulnerability in the barbuk theme's Python virtualenv prompt segment that allows local attackers to inject arbitrary terminal control sequences by embedding escape sequences in the requires-python field of a pyproject.toml file. When a user navigates into a directory containing a maliciously crafted pyproject.toml, the unfiltered field value is read via awk and concatenated directly into PS1 through __prompt-command without stripping control characters, causing injected OSC or CSI sequences to be written to and interpreted by the terminal emulator on every prompt render.
Risk Assessment
The risk includes potential arbitrary command execution or data theft by a local attacker who can exploit the vulnerability to take control of the user's terminal session.
Recommendation
Upgrade Bash-it to a patched version and avoid opening untrusted directories with pyproject.toml files.
