Affected versions of nw 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 nw.

Recommendation

Update to version 0.23.6-1 or later.
