CVE-2025-59252
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper neutralization of special elements used in a command ('command injection') in Copilot allows an unauthorized attacker to disclose information over a network.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA command injection vulnerability exists in Copilot where improper neutralization of special elements allows an unauthorized attacker to inject malicious commands, potentially leading to information disclosure over a network. The critical CVSS 9.3 score indicates ease of exploitation and significant impact.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Copilot availability in WordOpen Microsoft Word, look for the Copilot icon in the ribbon or right-click menu. Check if Copilot pane or features are present in the interface.Affected if Copilot is visible or accessible in the Word application
-
Check Microsoft 365 license statusOpen Word, go to File > Account to view the subscription information. Confirm if the account has a Microsoft 365 license that includes Copilot capabilities.Affected if A Microsoft 365 subscription with Copilot access is active
-
Inspect Copilot settingsIn Word, go to File > Options > Copilot (or search for Copilot in Options) to view Copilot-specific configuration settings.Affected if Copilot settings are configurable or enabled in the application
-
Check for recent Copilot usageReview recent documents or look for Copilot activity indicators in the Word interface, such as conversation history or generated content.Affected if Copilot features have been used recently on the system
If Copilot is present, enabled, or accessible in Microsoft 365 Word, the environment is affected by this vulnerability since all versions are impacted.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and sanitization for all user-supplied data that could reach system command execution points. Use parameterized APIs or safe library functions instead of shell commands, and apply principle of least privilege to limit potential disclosure impact.
