CVE-2026-35464

CVE-2026-35464 · pyLoad has an incomplete fix for CVE-2026-33509: unprotected storage_folder enables arbitrary file write to Flask session store and code execution

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

pyLoad is a free and open-source download manager written in Python. The fix for CVE-2026-33509 added an ADMIN_ONLY_OPTIONS set to block non-admin users from modifying security-critical config options. The storage_folder option is not in this set and passes the existing path restriction because the Flask session directory is outside both PKGDIR and userdir. A user with SETTINGS and ADD permissions can redirect downloads to the Flask filesystem session store, plant a malicious pickle payload as a predictable session file, and trigger arbitrary code execution when any HTTP request arrives with the corresponding session cookie. This vulnerability is fixed with commit c4cf995a2803bdbe388addfc2b0f323277efc0e1.
