CISA: Microsoft SharePoint flaw now exploited in ransomware attacks
CISA has confirmed that ransomware groups are actively exploiting a high-severity remote code execution vulnerability in Microsoft SharePoint, a flaw that has been flagged as under active attack since early July.
Why this matters: SharePoint is not a niche tool. It sits at the center of how many organizations share files, manage documents, and store internal information. A remote code execution flaw means attackers can run their own code on your systems without needing a password. Ransomware gangs are now doing exactly that. If your organization runs SharePoint and has not patched this, it is a live target. Patch it now, or assume someone is already inside looking around.
