Feds told to patch BeyondTrust flaw within 3 days after active exploitation

CISA ordered Federal civilian agencies to patch BeyondTrust Remote Support and Privileged Remote Access within three days after CVE-2026-1731, a remote code execution flaw that’s been actively exploited. SaaS instances were patched by BeyondTrust on Feb 2, 2026, but on-premise deployments require manual updates. Exploitation can allow unauthenticated remote code execution, risking system compromise, data exfiltration, and service disruption. Threat intel reports active exploitation and about 11,000 exposed instances (roughly 8,500 on‑premises). The agency added the CVE to its Known Exploited Vulnerabilities catalog and urged mitigations or discontinuation per vendor guidance under BOD 22-01.
