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.
