Portal For Arcgis

Missing authentication in Esri Portal for ArcGIS 12.1 and earlier (Windows, Linux, and Kubernetes deployments) exposes a critical API endpoint that a remote, unauthenticated attacker can reach directly, bypassing access controls to interact with functionality that should require an authenticated session. Esri rates this critical (CVSS 9.8) and disclosed it in its June 2026 ArcGIS security bulletin; no public exploit identified at time of analysis and it is not listed in CISA KEV. Because the exposed function is an administrative/portal API reachable over the network with no credentials, successful access could lead to disclosure or manipulation of portal content and configuration.

Account takeover in Esri Portal for ArcGIS 12.1 and earlier (Windows, Linux, and Kubernetes) stems from a weak forgotten-password recovery mechanism (CWE-640) that a remote, unauthenticated attacker can manipulate to assume ownership of another user's account. The flaw carries a CVSS 9.8 rating because it is network-reachable with no authentication or user interaction, yielding full compromise of confidentiality, integrity, and availability of the targeted account. There is no public exploit identified at time of analysis and EPSS is low (0.22%, 13th percentile), and CISA's SSVC framework records exploitation as none, indicating no observed in-the-wild activity despite the critical score.
