MITRE ATT&CK
2 techniques across 2 tactics: Initial Access, Credential Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | No special conditions - remote unauthenticated exploitation over the network against Azure AI Foundry (AV:N/AC:L/PR:N/UI:N). Exploitation requires the attacker to reach an Azure AI Foundry feature that fetches an attacker-influenced URL server-side. The primary limiting factor is that this is a Microsoft-operated cloud service: the fix is applied server-side by Microsoft with no customer action, so the exposure window is bounded by Microsoft's remediation timeline rather than by customer patching, and impact is confined to confidentiality (no integrity or availability effect, no scope change to other systems). |
| Impact | The vendor CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, 7.5 High) describes a remotely reachable, low-complexity, unauthenticated SSRF whose only impact is high confidentiality loss - integrity and availability are both N and scope is Unchanged. Note a labeling conflict: the description says the flaw lets an attacker 'elevate privileges,' but the CVSS impact metrics (C:H/I:N/A:N, S:U) describe pure information disclosure, not privilege elevation - this is Microsoft MSRC boilerplate phrasing and the vector, not the prose, should drive prioritization. No EPSS score, no CISA KEV listing, and no public exploit are present in the input: exploitation status is 'no public exploit identified at time of analysis.' There is no SSVC decision data supplied. Because Azure AI Foundry is a Microsoft-operated cloud service, the fix is almost certainly server-side and already applied for all tenants, which materially lowers real-world customer action risk even though the raw score is High. Net: a genuine but self-remediating SSRF-driven disclosure issue - real severity, low residual customer exposure once Microsoft ships the fix. |
| Exploit ScenarioDerived | An unauthenticated remote attacker sends a crafted request to an Azure AI Foundry endpoint that fetches a user-supplied URL, coercing the service into making server-side requests to internal Azure resources or the instance metadata endpoint and returning the response, disclosing sensitive internal data. No authentication or user interaction is required (PR:N/UI:N) and complexity is low (AC:L). No public proof-of-concept is identified at time of analysis. |

Alert meAnalysisAIv1 – Sep 17, 2026
Server-side request forgery in Azure AI Foundry allows remote unauthenticated attackers to cause high confidentiality loss by making the service fetch attacker-controlled URLs. Microsoft applies the fix server-side, requiring no customer action, and no public exploit has been identified at time of analysis.
RemediationAI
Microsoft addresses this vulnerability server-side; no customer action is required. Patch available per vendor advisory. Users should monitor the MSRC advisory for confirmation of remediation. No workarounds are necessary as the fix is applied automatically. Organizations using Azure AI Foundry should ensure that any custom URL-fetching features they have built on top of the service validate and restrict outbound requests, but the core service is patched by Microsoft. For the most current guidance, consult the vendor advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-85917.

Technical ContextAI · show details
Server-Side Request Forgery (SSRF) in Azure AI Foundry (CWE-918) occurs when the application fetches a remote resource without validating the user-supplied URL, allowing an attacker to coerce the server into making requests to arbitrary internal or external systems. This can lead to unauthorized access to sensitive information, such as cloud metadata endpoints or internal services. The vulnerability is remotely exploitable without authentication (AV:N/AC:L/PR:N/UI:N) and results in high confidentiality impact only, with no integrity or availability impact. The affected component is a feature within Azure AI Foundry that processes URLs server-side.

DescriptionCVE.org
Server-side request forgery (ssrf) in Azure AI Foundry allows an unauthorized attacker to elevate privileges over a network.
Executive ViewAI
A server-side request forgery flaw in Microsoft's Azure AI Foundry service (CVE-2026-85917, CVSS 7.5) could allow attackers to make the platform fetch attacker-controlled URLs, exposing sensitive data processed or held within customer AI workloads. Because this is a Microsoft-operated cloud service, the exposure is not something the organization can fix on its own - remediation sits with the vendor, and leadership should care primarily about what data in our AI Foundry environments could have been read by an unauthorized party and whether regulated or confidential information was in scope. No public exploit has been identified at time of analysis, but the vulnerability is rated HIGH for confidentiality loss and exploitation is a matter of vendor-side timing rather than our patch cycle.
No vendor-released patch identified at time of analysis; the advisory context indicates Microsoft remediates server-side with no customer action required. Interim mitigations: restrict outbound network egress for Azure AI Foundry workloads using allowlisting, firewall/NSG rules, and private endpoints; disable or constrain user-, prompt-, and model-supplied URL fetching (web grounding, connectors, custom tools/actions); monitor egress and service logs for requests to unknown external destinations; rotate credentials and connection strings reachable by the affected workloads; obtain written confirmation from Microsoft that the server-side fix covers the subscription and regions in use.
