🔴 The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned that a high-severity Apache ActiveMQ flaw, CVE-2026-34197, is being actively exploited in attacks. The bug, present for 13 years, allows authenticated attackers to execute arbitrary code via improper input validation and injection. Apache released patches on March 30 for ActiveMQ Classic 6.2.3 and 5.19.4, and CISA added the CVE to its KEV catalog, ordering federal agencies to patch by April 30.

⚠️ CISA has added CVE-2026-34197 to its Known Exploited Vulnerabilities catalog after active exploitation reports targeting Apache ActiveMQ Classic. The flaw is an improper input validation issue that can enable code injection via the Jolokia management API, potentially allowing arbitrary OS command execution. While the bug typically requires credentials, default credentials and a prior authentication bypass in some versions can render it effectively unauthenticated. Users should upgrade to ActiveMQ 5.19.4 or 6.2.3 to remediate the issue.

🔍 NIST will restrict enrichment in its National Vulnerability Database to the most critical CVEs, prioritizing entries in CISA’s Known Exploited Vulnerabilities (KEV), software used by the federal government, and other critical products. All other CVEs will be ingested but marked as not scheduled, and the agency will stop recalculating severity scores when submitters provide their own. The move follows a surge in submissions and a backlog of more than 30,000 CVEs, and NIST says it will adopt automation and delegate tasks to CNAs to stabilize NVD operations.
