Microsoft and others push out emergency patches for a critical flaw in Brotli, the C decoder library built into Node.js, that could allow remote code execution (Bill Toulas/BleepingComputer)

Emergency patches for a critical Brotli flaw in Node.js-linked infrastructure highlight how a single open-source component can create outsized operational and security risk across applications and services. For CIOs, the key implication is stronger dependency visibility and faster patch orchestration: IT teams need clear inventory of affected workloads, accelerated vulnerability response, and tighter controls around internet-facing systems that could be exposed to remote code execution or data theft.
