Week of July 6, 2026
This week brought a critical vulnerability in Microsoft SharePoint Server that could let attackers run malicious code on your system. If your business uses SharePoint, this needs your immediate attention. The threat landscape remains active, and delays in patching leave you exposed to real attacks.
Microsoft SharePoint Server Code Execution Vulnerability
Microsoft SharePoint Server has a serious flaw in how it handles data from untrusted sources. If someone with access to your network exploits this vulnerability, they can execute their own code on your servers without needing extra permissions. This means an attacker could install ransomware, steal files, or lock down your entire system. The vulnerability is real, it's being tracked, and attackers will look for unpatched servers.
Action: If you use SharePoint Server, apply Microsoft's security updates immediately. Check Microsoft's official guidance and patch before July 4th if you haven't already. If patches aren't available for your version, evaluate whether you can take that service offline or restrict who can access it.
Staying Protected Going Forward
One vulnerability can slip through even the best monitoring. That's why layered security matters. Two tools work hard to protect small businesses like yours:
Malwarebytes catches threats that traditional antivirus misses. It monitors your systems for suspicious behavior and blocks malware before it can spread. For small teams without dedicated IT staff, it's a practical second line of defense. Learn more about Malwarebytes.
LastPass handles password security across your team. Weak or reused passwords are how attackers get in after they've found a vulnerability. LastPass makes it simple for everyone to use unique, strong passwords without the headache of remembering them. Get started with LastPass.
Together, these tools reduce your risk when vulnerabilities like this one emerge.
