TL;DR: December’s Patch Tuesday includes 57 fixes, with two Critical vulnerabilities and high-risk issues in GitHub Copilot for JetBrains, Windows Cloud Files, Office, RRAS and Azure Monitor Agent, Absolute Security reports. Endpoint defenders have to weigh trust-chain exposure and resilience alongside severity when deciding what to patch first.
Editorial analysis by NHI Mgmt Group, based on content published by Absolute Security: “Microsoft December Patch Tuesday: Critical Fixes & Updates”.
By the numbers:
- Microsoft’s December 2025 Patch Tuesday delivers 57 security fixes.
- Microsoft identifies 53 Important vulnerabilities in the same release.
Key questions
Q: Why are vulnerabilities in developer tools so dangerous for security teams?
A: Developer tools sit inside trusted workflows where code, credentials, and access decisions meet.
Q: What breaks when a low-privilege local vulnerability becomes a system-level exploit?
A: The device’s user-level containment model breaks first, then the attacker can operate with broader authority on the host.
Q: How should teams prioritise Microsoft patches when multiple CVEs are involved?
A: Teams should rank Microsoft patches by the combination of exploit status, business impact, and affected control plane, not by CVSS alone.
Practitioner guidance
- Prioritise exploitable endpoint paths first Rank fixes by network reachability, privilege impact, and default deployment before processing the full patch backlog.
- Patch developer extensions and IDE tooling immediately Treat IDE plug-ins, AI coding assistants, and related developer add-ons as security-controlled software with the same urgency as runtime endpoints.
- Harden remote-access and monitoring roles Focus urgent remediation on RRAS, DirectAccess, legacy VPN servers, and agent-managed hosts because these services sit on high-trust paths.
Bottom line: The article’s main warning is that patch urgency now depends on where the flaw sits in the trust chain, not only on its severity score.

Patch prioritisation is now a trust-boundary exercise, not a severity-ranking exercise. The article shows that the most operationally dangerous issues are the ones that sit on trusted workflows, privileged services, or widely deployed endpoint components. That means patch queues should be ordered by exposure path, reachability, and privilege impact rather than by CVSS alone. Security teams that treat every Important issue the same will miss the ones that collapse multiple control assumptions at once.
A question worth separating out:
Q: How should organisations balance patch urgency with operational resilience?
A: Treat urgent remediation and change safety as two linked controls. Patch the highest-risk exposed issues first, but keep pilot testing, rollback readiness, and exception handling in place so the fix does not create a new outage. Resilience is what lets security teams move fast without losing control.
