Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev102, an authenticated non-admin user with the SETTINGS permission can configure WindowsPhoneNotify through /json/save_config by setting pushurl, pushid, and enabled. WindowsPhoneNotify.send in src/pyload/plugins/addons/WindowsPhoneNotify.py then uses http.client.HTTPConnection without pyLoad's pycurl destination validation. When a download completes, the global notification event causes a blind POST from the pyLoad server to the attacker-selected internal host, port, and path. The response is not returned, but the request can probe internal services, reach cloud metadata endpoints, or trigger state-changing internal HTTP endpoints. This issue is fixed in version 0.5.0b3.dev102.
