# Intel TDX MigTD: capture-replay bypass lets a privileged local attacker escalate

Link for people: https://infrastack.ai/live/CVE-2026-61473 (this .md is for agents)

Authentication bypass by capture-replay in the Intel TDX Migration TD (MigTD) reference software. Intel says a privileged system-software attacker with local access could use it to escalate privilege, with high confidentiality and integrity impact (CVSS 4.0 9.2). Fixed in MigTD 0.7.2.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:MigTD affected < 0.7.2 fixed 0.7.2

## How to check

Check the MigTD build you deploy (intel/MigTD reference software, or the MigTD binary your platform/cloud vendor ships): any version before 0.7.2 is affected. Ask your cloud or platform vendor whether their MigTD is built from 0.7.2 or later.

## Fix

Update MigTD to version 0.7.2 or later (intel/MigTD v0.7.2 release).

## From the sources

Authentication bypass by capture-replay in the MigTD for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
