Hey there! 👋
I was reviewing the codebase and noticed a potential security issue that I thought I'd flag and fix.
What I found
setup_tools.py: Thetarfile.extractall()method is used without validating the paths of the files inside the tarball. This is vulnerabWhat I changed
The fix is minimal and targeted — I added proper validation/sanitization where user-controlled or untrusted data enters sensitive operations. No changes to existing functionality or public APIs.
Testing
Ran the existing test suite locally, everything passes. The change is backward-compatible.
Happy to discuss if you have questions!
