In November 2023 we discovered an issue in the Go standard library’s net/http.Client that allowed an attacker who controls redirect targets on a server to exfiltrate authentication secrets. Soon after, we discovered a similar issue in net/http/cookiejar.Jar. The issues, collectively designated CVE-2023-45289, have now been fixed in Go 1.22.1 and Go 1.21.8, released on March 5, 2024. This blog post dives into the technical details behind those two bugs and the patch that addresses them.

How would your team stay connected if your primary communication network failed? To keep lines of communication open during emergencies, today’s leading organizations deploy out-of-band communication solutions alongside their main channels. An out-of-band (OOB) communication system exists outside an organization’s primary network. As a result, it enables team members to stay connected when main lines are compromised, corrupted, or otherwise unavailable.

Out-of-band communication systems are critical to keeping IT, operations, and security teams securely connected during emergencies and mission-critical scenarios. By equipping team members with a communication channel that exists outside the organization’s primary network, decision-makers and leaders can rest assured that their teams can collaborate effectively when main communication channels are inaccessible or have been infiltrated.

Contributing to open source software helps you develop new skills, gain real-world coding experience, interact with new technologies, and meet new people. But with so many open source projects to choose from — developers started some 52 million new projects on GitHub in 2022 alone — it can be difficult to figure out which repositories to contribute to. If you’re thinking about joining a new open source project in 2024, you’ve come to the right place.

Ask any community member who’s ever donned the moderator tag in a new forum and they’ll agree that handling a multitude of new general questions, technical queries, and troubleshooting scenarios can be challenging at first. However, thanks to the rise of AI-powered chatbots, there are a lot of new opportunities to find innovative ways to tackle these challenges. The Mattermost Peer-to-Peer Forum is a good example of a community consisting primarily of developers.
