Dependency attacks in 2026 with James Matchett

Josh chats with James Matchett from Cloudsmith about a new report they put out. It has some scary looking statistics in it about how organizations are using dependencies. There are some surprising numbers in there, but the story is really one of defense in depth. There's no single thing we can do here, it's all about knowing what you have every step of the way. It's easy to say, but certainly a challenge to do right. James is a ton of fun to chat with and filled with energy and knowledge. The show notes and blog post for this episode can be found at…

Sovereignty, policy, and OpenUK with Amanda Brock

Josh welcomes Amanda Brock from OpenUK to chat about sovereignty, policy, open source, and a whole host of other topics. Amanda has front row seat into how sovereignty decisions can affect a county and its open source. It seems sometimes like open source is a global phenomenon, but there are always country wide considerations. This is what the OpenUK is doing in the UK. The discussion is great and the things the OpenUK is dealing with will affect many of us moving forward, even if we would prefer to ignore our digital borders.

The curl summer of Bliss with Daniel and Stefan

Josh chats with Daniel and Stefan from curl about their summer of bliss. Curl stopped taking vulnerability reports for a month and nothing much happened really. Daniel and Stefan have a really pragmatic view of all the new LLM powered vulnerability detection tools. The cost of finding a vulnerability has dropped dramatically, but the cost of fixing those bugs hasn't changed. Taking some time off is important for anyone in the middle of these reports. Daniel and Stefan have some great experience and ideas on how to make this all happen. It's great advice for anyone working on software, not…

Finding difficult vulnerabilities with Jaya Baloo from AISLE

Josh chats with Jaya Baloo from AISLE about their vulnerability scanner. If you follow open source vulnerabilities AISLE is a name you've seen popping up recently. They have a vulnerability scanner that is outperforming most of the existing scanners like Mythos. Jaya gives us some insight into how this all works and why they're different. We also learn about some scary new attacks that can be conducted on LLM models. Jaya was a ton of fun and filled with insights.

CVEs vs Advisories with Paul Asadoorian

Josh chats with Paul Asadoorian about a tool he wrote called fettle and a recent report Paul published on CVEs. Fettle is a tool to help update and manage Linux systems. The big sell on this one is checking if your firmware is out of date. We then talk about a report Paul created that doesn't obsess over CVEs, but rather the vendor updates. It makes more sense to worry about advisories as those are actionable, where CVEs often are not. It's a great chat and Paul is a legend in the industry.

Maintaining EOL Open Source with Commonhaus and HeroDevs

Josh chats with Erin Schnabel and Rob Nalen about a new effort from Commonhaus and HeroDevs for maintaining end of life open source. This project, the Open Source Sustainability Initiative is a clever way to bring corporations and projects together for maintenance of new and old versions of open source projects. This is pretty new territory for everyone, this project is worth keeping an eye on because it has a very small scope initially. Other similar ideas have gigantic scopes that are almost certainly too large. The show notes and blog post for this episode can be found at…

Cleanup, Speedup, Levelup open source at e18e

Josh chats with James from e18e. This is a project that is working on improving Javascript packages by cleaning up, speeding up, and leveling up the dependencies. The way the e18e project handles this work is very human open source. It's all about building up connections and trust with the package communities, which is no small effort. James fills us in on what they're doing as well as how we can get involved. It's a truly amazing effort The show notes and blog post for this episode can be found at https://opensourcesecurity.io/2026/2026-08-e18e-james

VulnCheck's State of Exploitation Report with Patrick Garrity

Josh chats with Patrick Garrity about the VulnCheck State of Exploitation 1H-2026 report. Patrick explains the current trends we are seeing around vulnerabilities right now. While the number of CVEs is way up, the number of actually exploited vulnerabilities isn't growing year over year. This tells us there is a lot of FUD and hype. We also ask where are all the vulnerabilities that project Glasswing found. They should be going public by now, but we're not seeing that play out in the data.

It's not all technical solutions, there are non technical things we can do to help reduce the risk posed by our…

Abandoned open source with Josh Marpet

Josh welcomes Josh Marpet for a discussion about abandoned open source packages. Josh Marpet has a foundation called Value Chain Risk Institute that has a report discussion how to start measuring if an open source package might be abandoned.

Red Hat's Project Lightwell with Mo Duffy

Josh welcomes Mo Duffy from Red Hat to chat about project Lightwell. The idea is to leverage the resources and understanding Red Hat has built up over the years to help deal with the deluge of vulnerability reports that are overwhelming open source projects. Mo does a really good job of explaining why this is fundamentally a people problem, not a technology problem. But it's a people problem we can probably use technology to help. It will be interesting to see where Lightwell goes in the next few years. The show notes and blog post for this episode can be found at…

Open source verification with Sal Kimmich

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…

Vulnerability disclosure with Casey Ellis

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.

There are more supply chain attacks and compromises than ever before. There are some great resources for this planning, but as David tells us, it's really not that hard to put some plans together. It's easy to over-plan, David gives some great tips on getting started with our planning for an eventual incident.

About Open Source Security

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.

Open Source Security is a English tech & science podcast from Josh Bressers. Melo plays each episode straight from the publisher's own feed — no ads added, no account needed — and remembers where you stopped, in this browser only.
