CVE-2026-123814 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.4 (medium) and affects pyload; fixed in 0.5.0b3.dev102.

## Summary

pyLoad, a Python download manager, is affected through its WindowsPhoneNotify addon. An attacker with a low-privileged account that has the SETTINGS permission can remotely make the server send blind HTTP requests to internal hosts they choose, which can probe internal services or trigger state-changing internal endpoints, with limited confidentiality and integrity impact.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- pyload: fixed in 0.5.0b3.dev102
- pyload-ng (PyPI): through 0.5.0b3.dev101
  - No fix released.

## 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.
