Citrix Crisis: Zero-Days Under Fire.
Today’s cybersecurity landscape is buzzing with urgent zero-day vulnerabilities and active exploits. Citrix NetScaler is in the hot seat, while Microsoft grapples with SharePoint flaws. Plus, major AI developments are reshaping security protocols.
Citrix Crisis: Zero-Days Under Fire

Citrix is confirming that two critical zero-day vulnerabilities in its NetScaler products are being actively exploited. These vulnerabilities, CVE-2026-88771 and CVE-2026-88772, allow attackers to gain remote code execution and are prompting urgent patching efforts.
CISA has added these vulnerabilities to its Known Exploited Vulnerabilities Catalog, pushing federal agencies to prioritize remediation. Organizations using Citrix NetScaler as an edge device should act fast to secure their networks.
Microsoft's SharePoint Vulnerability Exploits

A recently patched SharePoint vulnerability, CVE-2026-65660, has been confirmed as actively being exploited. Microsoft is urging users to patch immediately, as attackers can execute arbitrary code with low-level access.
