What is CVE-2025-57751?

The pyLoad Download Manager, an open-source tool developed in Python, is susceptible to a denial-of-service vulnerability. This issue arises from inadequate validation of the 'jk' parameter received via the CNL Blueprint. As a consequence, user-provided input is allowed to execute directly, leading to potential server CPU saturation and unresponsiveness of the web interface. A patched version addressing this flaw is available in release 0.5.0b3.dev92.
