A live, actively targetable flaw in on-premises Microsoft Exchange is sitting unpatched on roughly 22,000 servers worldwide and for many small and mid-size businesses, the safety net (extended security support) runs out next month, turning a patching task into a hard deadline.
If you've been preparing your company for a CMMC Level 2 certification assessment, you may have heard some confusing news: the federal government has put CMMC Phase II on hold.
That part is true.
What isn't true is that CMMC has disappeared.
On July 13, 2026, the Department announced the immediate suspension of CMMC Phase II, which had been scheduled to begin November 10, 2026. At the same time, officials launched a 60-day review of the program. Phase I self-assessment requirements remain in place.
A pair of critical, unauthenticated zero-day vulnerabilities in Citrix NetScaler are being actively exploited right now and with roughly 23,000 internet-exposed devices worldwide, this is a "patch today, not next sprint" moment that shows exactly why continuous vulnerability management can't be a once-a-quarter checkbox for any growing business.
A newly disclosed vulnerability in WordPress Core, nicknamed Click2Shell, allows an attacker to take control of a WordPress website if a logged-in administrator simply opens a specially crafted link. No further clicks, prompts, or approvals are needed. WordPress fixed the issue in version 7.1.1 and backported the fix to every supported branch back to 4.7. Because proof-of-concept code is now public, any organization running WordPress should confirm its sites are updated today.
A newly detailed Linux kernel vulnerability, tracked as CVE-2026-43502 and nicknamed ZcopyReaper, allows an unprivileged local user to escalate to full root control by abusing a memory-handling error in the kernel's Reliable Datagram Sockets (RDS) component. The flaw has existed since Linux kernel 4.17, working exploit code has been published, and patched kernels are available from major distributions. Organizations running Linux servers, cloud workloads, or Linux-based appliances should confirm patch status now.
A newly documented malware family named KATARU is hijacking internet-facing Linux devices, including routers and other IoT equipment, by guessing weak or default Telnet passwords. Once inside, it takes root-level control, embeds itself so it survives reboots, and enlists the device in a Mirai-style botnet used for large-scale DDoS attacks. Any organization with connected devices that are exposed to the internet, unpatched, or protected by default credentials should review its exposure now.
A newly disclosed security issue affecting ConnectWise ScreenConnect could allow files to be transferred and executed during an active remote-support session without the authorization or confirmation normally expected in certain circumstances. ConnectWise has released ScreenConnect 26.6.5 to address the vulnerability, identified as CVE-2026-84869, and recommends affected organizations update as soon as possible.
