Denial-of-Service attack in pyLoad CNL Blueprint using dukpy.evaljs

Published Aug 21, 2025 · Updated Aug 21, 2025 · Assigned by GitHub_M

Description

pyLoad is the free and open-source Download Manager written in pure Python. The jk parameter is received in pyLoad CNL Blueprint. Due to the lack of jk parameter verification, the jk parameter input by the user is directly determined as dykpy.evaljs(), resulting in the server CPU being fully occupied and the web-ui becoming unresponsive. This vulnerability is fixed in 0.5.0b3.dev92.
