CVE-2026-44226

pyLoad: Unauthenticated traceback disclosure via global exception handler in WebUI

State: Published
Severity: 5.3 Medium
Published: May 11, 2026
Updated: May 11, 2026
Reserved: May 5, 2026

Description

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, pyload-ng WebUI returns full Python traceback details to clients on unhandled exceptions. Because /web/<path:filename> is reachable without authentication and renders attacker-controlled template names, an unauthenticated user can reliably trigger a server exception (for example by requesting a non-existent template) and receive internal stack traces in the HTTP response. This vulnerability is fixed in 0.5.0b3.dev100.
