CVE-2026-22769 affects Dell RecoverPoint for Virtual Machines (RP4VMs) and allows unauthenticated remote attackers to gain root-level OS access using hard-coded credentials embedded in the product. Exploitation requires no user interaction and no valid credentials, giving attackers full control over backup and recovery infrastructure. CISA requires federal agencies to patch by February 21, 2026; all organizations should isolate affected appliances, apply Dell's patch immediately, and audit for existing persistence.

CVE-2020-7796 is an unauthenticated SSRF vulnerability in Synacor Zimbra Collaboration Suite, triggered when the WebEx zimlet is installed and zimlet JSP processing is enabled. Attackers can force the Zimbra server to issue arbitrary internal HTTP requests, enabling access to backend services and cloud metadata endpoints. CISA has added this to its Known Exploited Vulnerabilities catalog with a federal remediation deadline of March 10, 2026.

CVE-2025-40536 is an authentication bypass vulnerability in SolarWinds Web Help Desk that allows unauthenticated remote attackers to access restricted application functionality without credentials.

CISA has added the flaw to its Known Exploited Vulnerabilities catalog and requires federal agencies to patch by February 15, 2026.

Microsoft's February 2026 Patch Tuesday addresses over 50 vulnerabilities including six zero-day flaws actively exploited in the wild. Critical fixes affect Windows Shell, MSHTML, Microsoft Word, Remote Desktop Services, Desktop Window Manager, and developer tools such as GitHub Copilot and VS Code. Administrators should urgently apply these patches to prevent privilege escalation, code execution, and denial-of-service attacks.

CVE-2026-21519 is a type confusion vulnerability in Microsoft's Desktop Window Manager that allows an authenticated local attacker to escalate privileges to SYSTEM on affected Windows systems. CISA has added the flaw to its Known Exploited Vulnerabilities catalog with a federal patch deadline of March 3, 2026, confirming active exploitation. Organizations should apply the latest Microsoft Windows cumulative updates immediately, prioritizing systems where standard users hold local logon rights.

CVE-2026-21514 is a privilege escalation vulnerability in Microsoft Office Word caused by the application's reliance on untrusted inputs in security decisions. An authenticated local attacker can open a crafted document to escalate from standard user to elevated privileges without additional user interaction. CISA has added this CVE to its Known Exploited Vulnerabilities catalog with a federal patch deadline of March 3, 2026.

CVE-2026-21510 is a protection mechanism failure in Microsoft Windows Shell that allows an unauthenticated attacker to bypass security features over a network.
