Summary

There is a SQL injection vulnerability in Esri ArcGIS Server versions 12.1 and earlier on Windows and Linux that may allow a remote attacker with privileges to access the service (which could, depending on the service being configured in a non-default access configuration “public”, include an anonymous attacker) to issue database specific functions that should not be allowed. A patch is provided for ArcGIS Server software in General Availability and Extended support status, which includes versions 12.1, 12.0, 11.5, 11.3, and 11.1. Other versions are in mature or retired status, which are not patch eligible. Users working with unlisted versions are advised to upgrade and apply the patch.

Severity

CVE-2026-69226 (GCVE-0-2026-69226)

Vulnerability from nvd – Published: 2026-10-13 16:06 – Updated: 2026-10-13 19:31

Title

Portal for ArcGIS has a security vulnerability

Summary

A flaw in Portal for ArcGIS allows unauthenticated users to create new accounts through the sharing endpoint even when self-service account registration is disabled (disableSignup=true). An attacker can bypass the intended restriction by manipulating the signup workflow, resulting in unauthorized account creation.

Severity

6.5 (Medium)

CVE-2026-10758 (GCVE-0-2026-10758)

Vulnerability from nvd – Published: 2026-09-25 20:49 – Updated: 2026-09-26 22:51

Title

Esri Lerc has a security vulnerability

Summary

Esri LERC is an open-source image or raster format which supports rapid encoding and decoding for any pixel type. A Heap based Out-of-Bounds Write via Integer Overflow in LERC versions 4.1.0 and earlier may allow a remote, unauthenticated attacker who can pass specifically crafted attacker controlled imagery to an application that uses LERC to crash the application, leading to a denial of service.

Severity

7.5 (High)

CVE-2026-69226 (GCVE-0-2026-69226)

Vulnerability from cvelistv5 – Published: 2026-10-13 16:06 – Updated: 2026-10-13 19:31

Title

Portal for ArcGIS has a security vulnerability

Summary

A flaw in Portal for ArcGIS allows unauthenticated users to create new accounts through the sharing endpoint even when self-service account registration is disabled (disableSignup=true). An attacker can bypass the intended restriction by manipulating the signup workflow, resulting in unauthorized account creation.

Severity

6.5 (Medium)

CVE-2026-10758 (GCVE-0-2026-10758)

Vulnerability from cvelistv5 – Published: 2026-09-25 20:49 – Updated: 2026-09-26 22:51

Title

Esri Lerc has a security vulnerability

Summary

Esri LERC is an open-source image or raster format which supports rapid encoding and decoding for any pixel type. A Heap based Out-of-Bounds Write via Integer Overflow in LERC versions 4.1.0 and earlier may allow a remote, unauthenticated attacker who can pass specifically crafted attacker controlled imagery to an application that uses LERC to crash the application, leading to a denial of service.

Severity

7.5 (High)
