CVE-2026-29778

pyLoad: Arbitrary File Write via Path Traversal in edit_package()

State: Published
Severity: 7.1 High
Published: Mar 7, 2026
Updated: Mar 9, 2026
Reserved: Mar 4, 2026

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.
