Severity: high

Downloads Resources over HTTP



Affected versions of libxl insecurely download an executable over an unencrypted HTTP connection.

In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running libxl.


The module author recommends installing the bindings using a pinned and verified version of SDK instead of the automated download. More information is available in the modules README.
