CISA warned on Wednesday that attackers have begun exploiting a high-severity Microsoft SharePoint remote code execution vulnerability patched in May. [...]

Editorial Analysis

Why it matters

Organisations slow to patch on-prem SharePoint face immediate compromise risk; CISA's KEV listing may also trigger compliance obligations under frameworks like NIS2 that mandate timely vulnerability remediation.

What to do

Verify that the May SharePoint patch (or applicable mitigations) is deployed across all on-prem SharePoint instances and add the associated IOCs to detection rules.

Board brief

A known SharePoint vulnerability is now under active attack; delayed patching exposes the company to ransomware and data-theft risk.
