CVE-2026-81573

If CodeMeter Runtime before 8.41a or 9.10 is configured as a server, the configuration command handler does not enforce network- origin restrictions. Commands intended only for local or same-network clients can therefore be executed by arbitrary remote peers. An attacker can read potentially sensitive configuration data and overwrite selected values in Server.ini. This does include the hash of the credentials for the CodeMeter WebAdmin, enabling WebAdmin takeover.
