According to a recent LinkedIn post from Censys, the company is drawing attention to a new “Rapid Response” advisory on two Microsoft SharePoint Server vulnerabilities. The post indicates that CVE-2026-55040 and CVE-2026-63520 can be chained to bypass authentication and enable remote code execution on vulnerable SharePoint servers.
The LinkedIn post notes that this exploit chain is already listed in CISA’s Known Exploited Vulnerabilities catalog and that a public proof-of-concept is available, while Microsoft has released patches. Censys reports observing roughly 329,000 SharePoint instances, of which about 21,000 on-premises deployments expose version numbers that may help identify risk.
The company’s post highlights recommendations for organizations running Internet-facing SharePoint, urging prioritization of patching and exposure review, and links to a detailed advisory. For investors, this emphasis on rapid threat intelligence and visibility into widely used enterprise software suggests Censys is positioned as a key player in vulnerability monitoring, which could support demand for its security analytics offerings as cyber risk remains a strategic concern for enterprises.
