The US Cybersecurity and Infrastructure Security Agency (CISA) has issued a directive requiring federal agencies to patch an actively exploited remote code execution (RCE) vulnerability in Ray software within three days to prevent ongoing attacks.

This Wire brief sits within Fusion42's coverage of Cybersecurity.

You must prioritise patching insecure software quickly to maintain government contracts and federal market trust. This deadline tightens the window for compliance and raises the cost of delayed security fixes for your business.
