Problem
Severity:
Medium| File:format.py:L4The
format.pyscript usesos.system(f"autopep8 ... {filename}")wherefilenameis derived fromglob.glob. Whileglob.globis generally safe, usingos.systemwith f-strings is a dangerous anti-pattern. If the repository is ever cloned or placed in a directory with maliciously named Python files (e.g., a file namedfoo.py; rm -rf /), it could lead to arbitrary command execution.Solution
Replace
os.systemwithsubprocess.runusing a list of arguments to avoid shell interpretation. For example:subprocess.run(['autopep8', '--max-line-length', '140', '--in-place', '--aggressive', '--aggressive', filename]).Changes
