CVE-2026-42315 Details
Description
pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, when passing a folder name in the set_package_data() API function call inside the data object with key "_folder", there is no sanitization at all, allowing a user with Perms.MODIFY to specify arbitrary directories as download locations for a package. This vulnerability is fixed in 0.5.0b3.dev100.
A path traversal vulnerability has been identified in pyLoad versions through 0.5.0b3.dev99. The issue arises in the set_package_data() API function, where folder names passed without proper sanitization allow users with modify permissions to specify arbitrary download locations. This vulnerability could be exploited to write files outside the intended download directory, potentially leading to unauthorized file access or modification.
Users are advised to update to pyLoad version 0.5.0b3.dev100, where this vulnerability has been fixed.
