SharePoint RCE Gives Admins a July 4 Patch Deadline
CISA has added Microsoft SharePoint Server CVE-2026-45659 to its exploited-vulnerabilities catalog, giving federal agencies until July 4 to apply mitigations and run forensic triage. The flaw was patched in May, but active exploitation means on-prem SharePoint teams should verify builds, review exposure, and check for compromise now.
BlueHammer Ransomware Flag Puts Microsoft Defender Patching Back on the Clock
CISA has updated the Microsoft Defender BlueHammer flaw, CVE-2026-33825, to mark it as used in ransomware campaigns. The flaw was patched in April, but the new flag gives Windows teams a fresh reason to verify Defender updates, endpoint telemetry, and local privilege escalation controls.
Daktronics Controller Flaws Put Public Digital Signs on Patch Watch
CISA is warning that flaws in Daktronics DMP-5000, VFC-DMP-5000, and DMP-8000 controller firmware could expose public display systems to root-level compromise. Operators of billboards, highway signs, venues, hospitals, and other connected displays should patch firmware, change default credentials, and verify that controllers are not reachable from the open internet.
PTC Windchill Exploits Put Manufacturing PLM Systems on Patch Clock
CISA added CVE-2026-12569, a critical PTC Windchill and FlexPLM remote code execution flaw, to its Known Exploited Vulnerabilities catalog with a June 28 deadline. The bug is being used to deploy JSP web shells against product lifecycle management systems that often sit deep inside manufacturing and engineering workflows.
CISA Gives UniFi OS and Lantronix Flaws a June 26 Patch Deadline
CISA added three Ubiquiti UniFi OS flaws and a Lantronix EDS5000 code-injection bug to its Known Exploited Vulnerabilities catalog, setting a June 26 remediation deadline for federal agencies. The risk is not just another CVE list: exposed network management interfaces can become a fast path to device control.
CISA’s June 23 Deadline Puts Cisco SD-WAN, Chrome, and Arista EOS on the Triage List
CISA’s June 23 remediation deadline covers three actively exploited flaws across Cisco Catalyst SD-WAN Manager, Google Chrome’s V8 engine, and Arista EOS. The useful move for security teams is not treating them as one patch chore, but triaging each layer: network control plane, browsers, and tunnel decapsulation paths.
Five Eyes Warns Frontier AI Could Compress Cyber Risk Into Months
Five Eyes cyber agencies warned on June 22 that frontier AI could transform offensive and defensive cyber operations on a months-long timeline. The guidance turns AI-enabled cyber risk into a board-level resilience issue, with practical pressure on patching, identity controls, legacy systems, incident response, and defensive AI use.
LiteLLM Exploit Puts AI Gateways on a June 22 Patch Deadline
CISA’s June 22 remediation deadline for CVE-2026-42271 puts LiteLLM AI gateways on the security team’s priority list. The flaw affects MCP test endpoints, can expose model-provider credentials, and may become unauthenticated RCE when chained with a Starlette host-header bypass.
LiteSpeed cPanel Flaw Puts Shared Hosting Servers on CISA’s Patch Clock
CISA added CVE-2026-54420, an actively exploited LiteSpeed cPanel plugin flaw, to its Known Exploited Vulnerabilities catalog. Shared hosting providers running CloudLinux or CageFS should move to the fixed plugin versions, check cPanel logs, and treat suspicious access as a possible root-level incident.
Splunk Enterprise Flaw Hits CISA’s Exploited-Vulnerability List
CISA added CVE-2026-20253 to its Known Exploited Vulnerabilities catalog after evidence of active exploitation, and Splunk now says it is aware of limited exploitation. Affected self-managed Splunk Enterprise 10.0 and 10.2 systems should upgrade or carefully apply the PostgreSQL sidecar mitigation.
