The fix
Microsoft publishes remediation for this across 2 product branches. The fixed build differs per Windows version, so the row that matters is the one matching the machine you are looking at.
| Windows version | Fixed in build | Update | Released |
|---|---|---|---|
| Windows Admin Center | 2.4.2.1 | configuration change | 2026-09-17 |
| Windows Admin Center in Azure Portal | 0.45.0.0 | configuration change | 2026-09-17 |
Having the KB is not the same as knowing whether a machine has it. Windows updates supersede each other, so the update you installed often covers a fix that shipped in an earlier one. Paste your build into the patch checker and it walks that chain for you.
What it is
External control of file name or path in Azure Portal Windows Admin Center allows an unauthorized attacker to disclose information locally.
