Technical details

A missing authentication vulnerability exists in Esri Portal for ArcGIS (versions 12.1 and earlier) across Windows, Linux, and Kubernetes deployments. The flaw is rooted in an unprotected API that fails to validate credentials before granting access to critical functions, categorized under CWE-640 (Weak Password Recovery Mechanism). A remote, unauthenticated attacker can exploit this over the network with low complexity and no user interaction. Successful exploitation could lead to a complete compromise of confidentiality, integrity, and availability. Esri has addressed this in their June 2026 Security Bulletin.
