wolfSSL Patches Critical Certificate Forgery Vulnerability Affecting Billions of Devices

wolfSSL version 5.9.1 patched a critical flaw (CVE-2026-5194) that allows attackers to use forged certificates to impersonate trusted servers.

**If you use devices or software built on wolfSSL (common in IoT, routers, industrial controllers, and embedded systems), make sure they are isolated from the internet and accessible from trusted networks only, then check with your device vendor for firmware updates that include wolfSSL version 5.9.1 to patch CVE-2026-5194. Be aware that older or unsupported devices may never get this fix, so network isolation and monitoring are your only protection for those.**
