Something similar would likely work on web apps as well. PoC Here's the code to test for the filter bypass: Here is a video POC: (this is a Loom POC, only users with the UUID of the video can see it) https://www.loom.com/share/b766ece5193842848ce7562fcd559256?sid=fd826eb6-0eee-4601-bf0e-9cfee5c56e9d Impact Any CLI tool or library using this package can be/will be vulnerable to Path traversal.
