Advisory

Affected versions of the pyLoad package are vulnerable to Denial of Service (DoS) attacks due to insufficient validation of JavaScript code in the Click'n'Load (CNL) Blueprint handler. The `/flash/addcrypted2` endpoint accepts a `jk` parameter containing JavaScript code that is directly passed to the `eval_js()` function, which executes it through either `dukpy.evaljs()` or `js2py.eval_js()` without any timeout or resource limitations.
