CVE-2026-81574 (GCVE-0-2026-81574)

Vulnerability from cvelistv5 – Published: 2026-08-27 07:11 – Updated: 2026-08-27 13:32

Title

Format String Vulnerability in Logger

Summary

In CodeMeter Runtime before versions 8.41a and 9.10, the logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information such as process memory and stack canaries. The attack works locally, for example by using cmu --set-proxy to set the proxy value, and remotely when combined with CVE-2026-81573 by setting General.ProxyServer and then triggering this vulnerability.

Summary

Automation Builder, Drive Application Builder, Virtual Drive, Virtual DrivePlus Impacted by multiple vulnerabilities in Wibu CodeMeter

Scope

5 vulnerabilities in this advisory, including CVE-2026-81574.

CVE-2026-81574

The logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information such as process memory and stack canaries. The attack works locally, for example by using cmu --set-proxy to set the proxy value, and remotely when combined with CVE-2026-81573 by setting General.ProxyServer and then triggering this vulnerability. CodeMeter Runtime is only affected by the vulnerabilities listed below if it is configured as a server. This is not the default. To verify the setting, check the profiling value IsNetworkServer: - IsNetworkServer=1: configured as a server (affected). - IsNetworkServer=0: not configured as a server

8.2 (High)
