Vulnerability Title
pyLoad: Unauthenticated traceback disclosure via global exception handler in WebUI
Source: NVD (National Vulnerability Database)
Vulnerability 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.
