🚨 CVE-2025-55315 changed the conversation for .NET teams. This isn’t just another patch cycle. A critical 9.9 severity vulnerability in http://ASP.NET Core exposed how something as low-level as HTTP request parsing can turn into a full-blown security issue — enabling request smuggling, privilege escalation, and data exposure. Once a framework reaches end-of-life, the equation changes: → Vulnerabilities keep getting discovered → Exploits keep evolving → But upstream fixes stop That’s where risk compounds — especially for teams still running older .NET versions. Upgrading is the long-term answer. But real-world systems don’t always move on release timelines. HeroDevs Never-Ending Support (NES) for .NET exist — to keep systems secure, compliant, and operational while teams modernize on their own schedule. Security isn’t just about reacting to the latest CVE. It’s about what happens after the patch. #dotnet #AppSec #OpenSourceSecurity #EOL #DevSecOps #HeroDevs
