Summary

Show ▼
CISA added the LiteSpeed cPanel user-end plugin flaw to KEV and ordered Federal Civilian Executive Branch agencies to secure systems within three days under BOD 26-04. The action raises compliance urgency across the federal civilian footprint because the vulnerability is actively exploited and can lead to root escalation on affected shared hosting servers. Agencies are being pushed to treat the flaw as an immediate remediation item rather than a routine patch.
