Cisco’s Twice-Monthly Patch Cadence Starts With Catalyst Center and ClamAV Fixes
Cisco’s first July security-advisory drop under its new twice-monthly cadence includes a Catalyst Center arbitrary-file-read flaw and seven ClamAV vulnerabilities affecting Cisco Secure Endpoint. The change gives network and security teams more predictability, but it also means Cisco infrastructure patch planning needs to become a standing operating rhythm, not a quarterly scramble.
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.
SimpleHelp Exploit Turns Remote Support Into a Credential Theft Pipeline
Attackers are exploiting CVE-2026-48558 in SimpleHelp to turn remote support access into a malware delivery path. Teams should patch, hunt for forged technician sessions, and rotate credentials exposed on managed endpoints.
AI Pentesting Is Finding Bugs Faster Than Teams Fix Them
Cobalt’s latest AI pentesting research shows security teams are testing AI apps more often, but serious LLM vulnerabilities still have the lowest fix rate of any category. The useful lesson is not to abandon automation, but to connect AI security tests to ownership, triage, and retesting.
Oracle E-Business Suite Exploit Puts Payments Systems on Patch Watch
Attackers are exploiting CVE-2026-46817, a critical Oracle E-Business Suite flaw affecting Oracle Payments, while Shadowserver is tracking roughly 950 internet-facing EBS instances associated with exposure. Teams should verify May 2026 patches, review iPayment endpoint access, and check logs for suspicious file-transmission activity.
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.
FCC Turns Emergency Alert Cybersecurity Into a Baseline Requirement
The FCC adopted targeted cybersecurity rules for Emergency Alert System participants after years of warnings about default passwords, unpatched gear, and internet-exposed alerting equipment. Broadcasters and cable operators will have 60 days after Federal Register publication to meet the new baseline.
Anthropic’s Mythos Test Shows Why AI Cyber Defense Is Becoming Classified Work
An Anthropic Mythos test with U.S. intelligence agencies reportedly found vulnerabilities in highly sensitive government systems within hours. The episode sharpens the policy problem around frontier AI: the same models that can help defenders fix critical software can also compress the timeline for attackers.
