What is CVE-2026-33509?

The pyLoad download manager is susceptible to a security flaw that permits users with limited SETTINGS permissions to modify crucial configuration options without proper validation. Specifically, the set_config_value() API endpoint is exploitable, enabling non-admin users to alter the reconnect.script configuration. This setting can be directed to any executable on the file system, leading to potential remote code execution. A mere hardcoded validation for the general.storage_folder is in place, while other critical settings remain exposed and writable. This vulnerability has been addressed in pyLoad version 0.5.0b3.dev97, ensuring enhanced security measures.
