Esri vulnerabilities and threats

CVE-2026-69225 is an information disclosure vulnerability in Esri Portal for ArcGIS versions 11.5 through 12.0 and earlier. It allows a remote, unauthenticated attacker to cause sensitive information to be reflected in an HTTP response body. The vulnerability is classified under CWE-200, indicating exposure of sensitive information to unauthorized actors. The CVSS v3.1 base score is 5.9, reflecting a medium severity level.

CVE-2026-69238 is a low-severity cross-site scripting (XSS) vulnerability in Esri Portal for ArcGIS versions 11.1 through 11.5. It allows a remote attacker with high privileges to inject arbitrary HTML into the Portal for ArcGIS Home application. This vulnerability affects versions from 11.1 up to and including 11.5. Users are advised to patch or upgrade to the latest long-term support release to mitigate the issue.

CVE-2026-69224 is an information disclosure vulnerability in Esri Portal for ArcGIS versions 11.1 through 12.0. Under difficult to reproduce conditions, a remote unauthenticated attacker may cause sensitive information to be reflected in an HTTP response body. The vulnerability has a medium severity rating with a CVSS score of 5.9.

Esri Portal for ArcGIS versions 12.1 and earlier on Windows, Linux and Kubernetes have a missing authentication for critical function vulnerability allows a remote, unauthenticated attacker to access an unprotected API. The following versions are known to be affected: Portal for ArcGIS 12.1 and earlier. Other unsupported versions may also be affected. Esri recommends that users apply the Portal for ArcGIS Security 2026 Update 2 Patch to remediate this vulnerability.

A Weak Password Recovery Mechanism for Forgotten Password exists in Esri Portal for ArcGIS versions 12.1 and earlier on Windows, Linux and Kubernetes. A remote, unauthorized attacker may assume ownership of a user’s account by manipulating this mechanism. ArcGIS Administrators should configure an email server with ArcGIS Enterprise to facilitate user self-service password recovery. The ability for an administrator to reset a user’s password remains unchanged.

Esri ArcGIS Server contains a directory traversal vulnerability. ArcGIS Enterprise on Kubernetes is not impacted. An unauthenticated attacker could exploit this issue by sending crafted path parameters. Successful exploitation could allow overwriting sensitive files on the system. Abuse of this issue can allow full administrative access to ArcGIS Server, with high impact to confidentiality, integrity, and availability. This issue impacts all versions of ArcGIS Server on Windows and Linux 12.0 and prior. This issue does not impact ArcGIS Enterprise for Kubernetes.

Esri ArcGIS Server contains an unrestricted file upload vulnerability. An unauthenticated attacker could exploit this issue by uploading a crafted file to the affected endpoint. Successful exploitation could allow arbitrary file upload, potentially allowing for other attacks. This issue impacts all versions of ArcGIS Server on Windows and Linux 12.0 and prior. This issue does not impact ArcGIS Enterprise for Kubernetes.

CVE-2026-2813 is an open redirect vulnerability in Esri ArcGIS Server version 11.5. It arises from insufficient input validation in the login redirection workflow, allowing an authenticated attacker to craft requests that redirect users to untrusted sites. The impact is limited to confidentiality under specific user interactions and does not affect server-side components or other security boundaries. The vulnerability has a medium severity rating with a CVSS score of 4.7. No official patch or remediation guidance has been provided yet by the vendor.

CVE-2026-2812 is an improper authentication vulnerability in Esri ArcGIS Server affecting versions 12.0 and earlier. It involves an undocumented administrative endpoint that allows unauthenticated attackers to send crafted requests. Exploitation can disrupt the web-based browsing interface but does not impact confidentiality or availability. The vulnerability has a medium severity with a CVSS score of 5.3. No official patch or remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.

An incorrect authorization vulnerability exists in Esri Portal for ArcGIS 11.4, 11.5 and 12.0 on Windows, Linux and Kubernetes that did not correctly check permissions assigned to developer credentials.

An incorrect privilege assignment vulnerability exists in Esri Portal for ArcGIS 11.5 in Windows and Linux that allows highly privileged users to create developer credentials that may grant more privileges than expected.

There is a Cross‑Site Scripting (XSS) issue in Esri ArcGIS Pro versions 3.6.0 and earlier. ArcGIS Pro is a desktop application, and exploitation is limited to local users interacting with the application; no privileged role or elevated permissions are required beyond standard local user access. A local attacker can supply malicious strings that may be rendered and executed when a specific dialog within ArcGIS Pro is opened. This issue is fixed in ArcGIS Pro version 3.6.1.

There is a stored cross site scripting issue in Esri ArcGIS Server 11.4 and earlier on Windows and Linux that in some configurations allows a remote unauthenticated attacker to store files that contain malicious code that may execute in the context of a victim’s browser.

There is a stored cross site scripting issue in Esri ArcGIS Server 11.4 and earlier on Windows and Linux that in some configurations allows a remote unauthenticated attacker to store files that contain malicious code that may execute in the context of a victim’s browser.

ArcGIS Server versions 11.5 and earlier on Windows and Linux do not sufficiently validate uploaded files, enabling a remote unauthenticated attacker to upload arbitrary files to the server’s designated upload directories. However, the server’s architecture enforces controls that restrict uploaded files to non‑executable storage locations and prevent modification or replacement of existing application components or system configurations. Uploaded files cannot be executed, leveraged to escalate privileges, or used to access sensitive data. Because the issue does not enable execution, service disruption, unauthorized access, or integrity compromise, its impact on confidentiality, integrity, and availability is low. Note that race conditions, secret values, or man‑in‑the‑middle conditions are required for exploitation.
