Active exploitation in the wild means unpatched systems are already being targeted, making delayed remediation a direct operational and security risk. CISA's issuance of a Binding Operational Directive underscores how organizations — particularly federal agencies — often lack mature emergency patching processes capable of responding within tight windows.
