CVE-2026-44226 Details
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.
A vulnerability in pyLoad WebUI prior to version 0.5.0b3.dev100 allows for unauthenticated users to access full Python traceback details on unhandled exceptions. The issue arises because the template-rendering route is accessible without authentication and can be manipulated to trigger server exceptions, such as by requesting a non-existent template. This results in the internal stack traces being exposed in the HTTP response, disclosing implementation details that could aid in exploiting other vulnerabilities.
Users are advised to update to pyLoad version 0.5.0b3.dev100 or later.
