State: Published
Severity: 6.5 Medium

Description

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, the fix for CVE-2026-33509 prevents setting storage_folder inside PKGDIR or userdir, but does NOT protect the Flask session directory (/tmp/pyLoad/flask). An authenticated attacker can set storage_folder to the session directory and download session files of other users via /files/get/, leading to account takeover. This vulnerability is fixed in 0.5.0b3.dev100.
