CISA Adds Ivanti EPMM CVE-2026-1340 to KEV — Federal Patch Deadline Today
CISA has added CVE-2026-1340, a critical unauthenticated remote code execution flaw in Ivanti Endpoint Manager Mobile, to the Known Exploited Vulnerabilities catalogue with a federal agency deadline of 11 April. The vulnerability chains with CVE-2026-1281 to enable full appliance takeover and has been actively exploited since January 2026.

NIS2 Moves From Grace Period to Enforcement — Germany's BSI Registration Deadline Is Now
Eighteen months after the NIS2 transposition deadline, EU member states are moving from legislative implementation to active supervisory enforcement. Germany's BSI has set April 2026 as the registration deadline for essential and important entities under the national NIS2 implementation (NIS2UmsuCG). Organisations still treating NIS2 as a future requirement face immediate regulatory exposure as national competent authorities begin audit and penalty activity.
Apache ActiveMQ CVE-2026-34197: 13-Year-Old Jolokia API Flaw Enables Unauthenticated RCE
A critical unauthenticated remote code execution vulnerability in Apache ActiveMQ's Jolokia management API allows attackers to execute arbitrary OS commands by invoking a management MBean. CVE-2026-34197 roots in a design flaw present since ActiveMQ 5.x and chains dangerously with CVE-2024-32114. Patches are available in ActiveMQ 6.2.3 and 5.19.4.
BlueHammer Windows LPE Zero-Day Gives Attackers SYSTEM Access — No Patch Available
A publicly disclosed zero-day local privilege escalation vulnerability in Windows Defender's signature-update mechanism allows any authenticated user to escalate to SYSTEM. Named BlueHammer by researchers at Cyderes, the flaw has a working public exploit and no Microsoft patch as of publication. Security teams should implement interim mitigations immediately.
CIRCIA Final Rule Expected May 2026: What Critical Infrastructure Operators Must Do Now
CISA is expected to publish the long-awaited CIRCIA final rule in May 2026, mandating 72-hour cyber incident reporting and 24-hour ransomware payment reporting for critical infrastructure sectors. With weeks remaining, organisations that have not started preparing face significant compliance and legal exposure when the rule takes effect.
CISA Supplemental Direction ED 26-03: How to Hunt for Compromise in Cisco Catalyst SD-WAN

Cisco Discloses Two CVSS 9.8 Vulnerabilities Affecting Enterprise Server and Licence Infrastructure
Cisco has patched two critical unauthenticated remote code execution and authentication bypass flaws in widely-deployed enterprise infrastructure. Organisations running Cisco UCS rack servers or managing software licences on-premises face complete compromise of affected systems if patches are not applied urgently.
North Korean State Actors Poisoned 1,700+ Open-Source Packages Used by Your Development Teams
