CVE-2026-109467

Summary

CVE-2026-109467 is an improper authentication flaw in Azure DevOps that allows an authenticated attacker to bypass expected authorization checks and execute arbitrary code over the network. This violates the principle of least privilege and enables lateral movement or full system compromise.

Exploitability

Exploitation requires valid low-privilege credentials and network access to affected endpoints; no public exploit is known, but the CVSS attack vector (AV:N/AC:L/PR:L) indicates it is straightforward for authenticated attackers.

Blast radius

Successful exploitation could lead to full confidentiality and integrity compromise of Azure DevOps services, including unauthorized code execution, data exfiltration, and potential compromise of CI/CD pipelines and associated infrastructure.

Detection

Defenders should monitor Azure DevOps audit logs for anomalous API calls from low-privilege users to privileged endpoints (e.g., /_apis/distributedtask/hubs, /_apis/build/requests) with unexpected method or payload patterns; also watch for unusual outbound network connections from build agents or pipeline runners.

Prioritized remediation

No fixed version or patch level is specified in the published description; apply Microsoft’s official security advisory guidance immediately—restrict access to Azure DevOps endpoints to trusted networks only and disable non-essential authentication pathways until patched.
