CVE-2026-123814

pyLoad WindowsPhoneNotify addon: non-admin SETTINGS user triggers SSRF via unguarded http.client notification host

Published Nov 9, 2026 CVSS 3.1 · 6.4 Medium EPSS < 1% KEV · Not listed
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.
