IPython provides an interactive Python shell and Jupyter kernel to use Python interactively. Versions prior to 8.10.0 are vulnerable to command injection in the set_term_title function under specific conditions. This has been patched in version 8.10.0.
Users are only vulnerable when calling this function in Windows in a Python environment where ctypes is not available. The dependency on ctypes in IPython.utils._process_win32 prevents the vulnerable code from ever being reached (making it effectively dead code). However, as a library that could be used by another tool, set_term_title could introduce a vulnerability for dependencies. Currently set_term_title is only called with (semi-)trusted input that contain the current working directory of the current IPython session. If an attacker can control directory names, and manage to get a user to cd into this directory, then the attacker can execute arbitrary commands contained in the folder names.
