Josh chats with Sal Kimmich about the current state of everything, and what we can expect next. Sal has some incredible insight into what we can expect to see due to the current wave of security bugs and incidents. There are some new features we will need in both our hardware and software to ward off the state of things. Since those features are years away, what we need in the short term is shoring up our SDLC programs. Sal has some really good medical examples and analogies for this one. It's a huge problem but not insurmountable. The show notes and blog post for this episode can be found at https://opensourcesecurity.io/2026/2026-06-verification-sal-kimmich/

Josh talks to Casey Ellis about why vulnerability disclosure is so hard, and also so important. Casey is one of the best in this space having been a Bugcrowd founder. There are few people with more experience and insight into how a security vulnerability should be handled, and why the explosion of AI is making all this much harder than it's ever been before. While finding vulnerabilities is easy, reporting them is still a lot of work. Casey is working on helping everyone better understand all this with his disclose.io project.

Josh talks to Hans-Christoph Steiner about F-Droid, the Free and Open Source Android App Repository. The way F-Droid works looks a lot like a Linux distribution which has some interesting security challenges, but also some great security benefits. Hans walks us through the current state of open app repositories and also what the future currently looks like. There are more open phones than ever before, but there are also more challenges than ever before. Hans breaks it all down in an easy to understand way.

Josh has a discussion with Vlad-Stefan Harbuz about the Open Source Pledge as well as his recent FOSDEM talk. The Open Source Pledge is all about trying to build a sustainable universe for open source maintainers. This ties into Vlad's FOSDEM talk which was all about the challenge of just knowing what open source you are using. The importance of trying to make open source sustainable is a really important topic, but it's also a really hard topic. Vlad helps explain all of this as well as some ideas for the solving this in the future.
