CVE-2026-123813
pyLoad: Privilege revocation and password change through the REST API do not invalidate the user's session
Description
pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev102, pyLoad does not invalidate existing Flask sessions when an administrator changes a user's permissions or password through /api/set_user_permission or /api/change_password. Api.set_user_permission and Api.change_password update the database, but session authorization continues to use role and permission values copied at login by set_session in webui/app/helpers.py. A user can therefore retain revoked privileges or continue using a session established with an old password for the configured session lifetime. API-key authentication is not affected because that path rereads user data from the database. This issue is fixed in version 0.5.0b3.dev102.
