{"id":"CVE-2026-29778","summary":"pyLoad: Arbitrary File Write via Path Traversal in edit_package()","details":"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.
