Vulnerability Title
pyLoad: Arbitrary File Write via Path Traversal in edit_package()
Source: NVD (National Vulnerability Database)
Vulnerability Description
pyLoad is a free and open-source download manager written in Python. From version 0.5.0b3.dev13 to 0.5.0b3.dev96, the edit_package() function implements insufficient sanitization for the pack_folder parameter. The current protection relies on a single-pass string replacement of "../", which can be bypassed using crafted recursive traversal sequences. This issue has been patched in version 0.5.0b3.dev97.
