Esri Portal for ArcGIS < Security 2026 Update 2 Multiple Vulnerabilities

critical Nessus Plugin ID 330655

Synopsis

The remote host is missing one or more security updates.

Description

The version of Esri Portal for ArcGIS installed on the remote host is missing Security 2026 Update 2 Patch. It is, therefore, affected by multiple vulnerabilities:

 - A missing authentication for critical function vulnerability allows a remote, unauthenticated attacker to access an unprotected API. (CVE-2026-13019)

 - A weak password recovery mechanism for forgotten password allows a remote, unauthorized attacker to assume ownership of a user's account by manipulating this mechanism. (CVE-2026-13020)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Apply the Security 2026 Update 2 patch for Esri Portal for ArcGIS.
