Hello, Mattermost community! We’re thrilled to announce the release of the Mattermost AI Copilot beta, a groundbreaking addition to the Mattermost platform. This plugin is not just a tool.

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.
