Aaron Frost explores the overly complex world of vulnerability identifiers for end of life software. We discuss how incomplete CVE reporting creates blind spots for users while arming attackers with knowledge. The conversation uncovers the ethical tensions between resource constraints and security transparency, highlighting why the "vulnerable until proven otherwise" approach is the best path forward for end of life software.

Open Source Security is a media project to help showcase and educate on open source security. Our goal is to give the community a platform educate both developers and users on how open source security works.
There’s a lot of good work happening that doesn’t get attention because there’s no marketing department behind it, they don’t have a developer relations team posting on LinkedIn every two hours. Let’s focus on those people and teams then learn what they do and how they do it. The goal is to hear from the people doing the work, they know what’s up, they have a lot to teach us. We just have to listen.
