No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 issues handles per connection and relies on a cryptographically weak SID as sole authenticator. An attacker can brute-force the SID, recover another session's handle number, and read license information belonging to another handle.
