Details

As written in the advisory (Markdown source, shown as plain text).

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](https://github.com/ipython/ipython/blob/3f0bf05f072a91b2a3042d23ce250e5e906183fd/IPython/utils/terminal.py#L103-L117) under specific conditions. This has been patched in version 8.10.0. ### Impact Users are only vulnerable when calling this function in Windows in a Python environment where [ctypes](https://docs.python.org/3/library/ctypes.html) 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.
