Server-side request forgery (ssrf) in Microsoft Copilot in Azure allows an authorized attacker to disclose information over a network.
AnalysisAI
Server-side request forgery in Microsoft Copilot in Azure enables any authenticated Azure user to coerce the service into issuing arbitrary outbound requests, disclosing internal or cloud-infrastructure data back through the Copilot response channel. The CVSS scope-change indicator (S:C) and high confidentiality impact (C:H) suggest the service's privileged network position can be leveraged to reach resources beyond the application boundary - such as Azure Instance Metadata Service endpoints, internal APIs, or adjacent cloud services. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Azure account with at minimum low-level access rights to Microsoft Copilot in Azure (PR:L per CVSS vector) - unauthenticated external attackers cannot exploit this vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.7 High score is supported by a credible vector: AV:N (fully network-exposed), AC:L (no special conditions required beyond authentication), PR:L (any low-privilege Azure account suffices), UI:N (no victim interaction needed), S:C (scope change - forged requests reach external security domains), C:H (high confidentiality breach via disclosed internal data), I:N/A:N (integrity and availability unaffected). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Microsoft has released a patch per vendor advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-69855; as Microsoft Copilot in Azure is a cloud-managed service, the fix is applied server-side and customers should verify with Microsoft that their tenant is running the patched build - no exact customer-installable version number is independently confirmed from available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, apply Microsoft's released patch to all Azure Copilot deployments and audit Copilot access logs for suspicious outbound requests or unusual network activity. …
