Discourse continues to make news after researchers discovered a vulnerability that enabled attackers to invoke OS commands at the Administrator level. The open-source platform has released a critical bug fix that CISA strongly urges everyone to install if they are running Discourse software.

It’s critically important for both systems administrators and individual users to keep up with security information from software providers, and to install patches promptly. We can’t rely on Microsoft or other OS vendors to automatically push patches to our systems. Users of Discourse software should test and install this patch as their most important priority.

Level 10 bugs are undoubtedly the most serious vulnerabilities. Discourse is a major communications platform. Ensuring security and robustness is paramount. This highlights the need to continue to invest in the next generation of cyber security professionals. We have the tools to find them even in a tight labor market. We need to find them and get them into the fight as soon as possible to ensure we have a strong workforce capable of managing vulnerabilities like this as well as those to come.
