CVE-2026-23659: Azure Data Factory Information Disclosure Vulnerability
Exposure of sensitive information to an unauthorized actor in Azure Data Factory allows an unauthorized attacker to disclose information over a network.
Security readout for executives and security teams
Plain-English summary
Microsoft lists CVE-2026-23659 as a high-severity Azure Data Factory information disclosure issue. The source says an unauthorized network attacker could disclose sensitive information. The business concern is exposure of confidential data in or reachable through Azure Data Factory workflows.
Executive priority
Treat this as a high-priority cloud data confidentiality risk. Prioritize verification and Microsoft-directed remediation for environments where Azure Data Factory handles sensitive, customer, or regulated data.
Technical view
The CVE is CWE-200 with CVSS 3.1 score 8.6: network reachable, low complexity, no privileges, no user interaction, changed scope, high confidentiality impact, no integrity or availability impact. Affected product detail is limited to Microsoft Azure Data Factory.
Likely exposure
Organizations using Azure Data Factory should assume potential exposure until they verify Microsoft guidance. The bundle does not identify specific versions, regions, configurations, tenants, pipelines, or integration runtime types.
Exploitation context
The bundle marks KEV as false and the CVSS vector lists exploit maturity as unproven. No supplied source states active exploitation or public exploit availability.
Researcher notes
Evidence is sparse beyond the CVE metadata and MSRC reference. Do not infer a vulnerable configuration or exploit path from the CVSS vector alone. Track MSRC for precise affected conditions and remediation mechanics.
Mitigation direction
Review the MSRC advisory for official remediation details.
Apply Microsoft-provided patches or service mitigations named by MSRC.
Inventory Azure Data Factory usage across all Azure tenants.
Prioritize workflows handling credentials, customer data, or regulated information.
Validation and detection
Confirm whether Azure Data Factory is deployed in each tenant.
Check MSRC for the current CVE status and remediation guidance.
Record affected subscriptions, data factories, and sensitive linked workflows.
Verify remediation evidence through Azure change records or vendor status.

CWE-200: Information exposure and cloud metadata lookup
Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
