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.
Apple’s Early Security Updates Show AI Is Shrinking Patch Windows
Apple pushed iOS 26.5.2, iPadOS 26.5.2, macOS Tahoe 26.5.2, and Safari 26.5.2 out before the broader 26.6 release cycle, citing AI-driven security concerns. The update is a practical reminder that patch timing now matters as much as patch content.
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.

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.
Cisco Unified CM Exploit Gives Voice Servers a June 28 Patch Deadline
CISA gave federal agencies until June 28 to fix CVE-2026-20230, a Cisco Unified Communications Manager SSRF flaw that can write files and lead to root access when WebDialer is enabled. Enterprise teams should treat it as a voice-infrastructure exposure check, not just another Cisco patch.
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.
