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.

  • GHSA-6px9-j4qr-xfjwpyLoad has an Arbitrary File Write via Path Traversal in edit_package()2026-03-05ghsa · osvUS

    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. Exploitation An authenticated user with MODIFY permission can bypass the sanitization by submitting a payload such as: `pack_folder=..././..././..././tmp` After the single-pass replacement, this becomes: `../../../tmp` Because the traversal sequences are not properly validated, the resulting normalized path escapes the intended storage directory and writes files to /tmp or other locations.
