Wibu develops software licensing and code-protection solutions centered on its CodeMeter platform, a modestly represented but strategically deployed toolset that sits deep in the supply chains of industrial automation, engineering software, and enterprise licensing infrastructure. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity, reflecting the memory-safety and input-validation challenges inherent to a protective runtime that must parse untrusted license tokens and manage system-level resources. The exposure recurs across CodeMeter variants—including the runtime, administrative interfaces, and hardware key drivers—through weakness classes including out-of-bounds reads and writes, cross-site scripting in web-facing components, and improper resource management, which carry particular weight because flaws in licensing enforcement can undermine the vendor's core protective mission. Defenders should treat CodeMeter deployments as high-priority targets for patching, especially in air-gapped or industrial environments where updates lag; live severity, exploitation, and exposure counts are shown alongside this summary.
