CVE-2026-75597

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev101, the `/web/<path:filename>` route in `src/pyload/webui/app/blueprints/app_blueprint.py` renders Jinja2 templates without any authentication requirement. Every equivalent direct route (`/logs`, `/settings`, `/queue`, `/dashboard`, etc.) is protected by `@login_required`, but the underlying templates for all of these pages are accessible unauthenticated via this endpoint. Combined with an exception attribute typo in `src/pyload/webui/app/handlers.py` (`exc.desc` instead of `exc.description`), internal Jinja2 variable names are leaked in HTTP 500 response bodies to unauthenticated callers. An attacker can also enumerate all valid template names by observing 200 vs 500 response differentiation. Version 0.5.0b3.dev101 contains a patch.
