Summary
pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev97, the ADMIN_ONLY_CORE_OPTIONS authorization set in set_config_value() uses incorrect option names ssl_cert and ssl_key, while the actual configuration option names are ssl_certfile and ssl_keyfile. This name mismatch causes the admin-only check to always evaluate to False, allowing any user with SETTINGS permission to overwrite the SSL certificate and key file paths. Additionally, the ssl_certchain option was never added to the admin-only set at all. This vulnerability is fixed in 0.5.0b3.dev97.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
