CVE-2026-115712 in Cloud Enterprise
Summary
by MITRE • 10/29/2026
Incorrect Authorization (CWE-863) in Elastic Cloud Enterprise (ECE) can lead to unauthorized modification of platform-level settings via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with read-only access to the platform can change an installation-wide account setting that only platform administrators are permitted to change.

The vulnerability identified as CWE-863, Incorrect Authorization, represents a critical flaw in the Access Control List implementation within Elastic Cloud Enterprise. This specific issue allows authenticated users who possess only read-only permissions for the platform to execute actions that should be strictly reserved for platform administrators. The core technical failure lies in the application's inability to properly constrain access to sensitive functionality based on the user's assigned role or privilege level. Instead of validating whether the requesting entity has administrative rights before processing a request to modify installation-wide account settings, the system accepts and executes these commands from users with significantly lower privileges. This breakdown in authorization logic effectively bypasses the intended security boundaries established by the platform's identity and access management framework.
From an operational perspective, this vulnerability enables unauthorized modification of critical platform-level configurations. These settings often dictate fundamental aspects of how the Elastic Cloud Enterprise environment operates, including authentication mechanisms, logging policies, or integration parameters that affect all users within the system. An attacker exploiting this flaw could alter these global settings to degrade security posture, disrupt service availability, or create backdoors for further exploitation. For instance, changing account settings might disable multi-factor authentication requirements, weaken password complexity rules, or modify audit logging configurations to hide malicious activities. The impact is severe because it compromises the integrity of the entire platform infrastructure rather than just a single tenant's data, potentially affecting all organizations hosted on that Elastic Cloud Enterprise installation.
This vulnerability aligns with CAPEC-1, Accessing Functionality Not Properly Constrained by ACLs, which describes attacks where an adversary exploits insufficient access controls to perform privileged actions. The attack vector typically involves the attacker authenticating to the platform with a standard user account and then sending crafted API requests or interacting with web interfaces that trigger the modification of administrative settings. Since the vulnerability resides in the authorization logic rather than input validation, traditional injection-based defenses may not detect this activity unless they are specifically tuned for privilege escalation patterns. The lack of proper constraint checking means that even if other security controls like encryption and network segmentation are robust, the internal application logic remains vulnerable to abuse by any authenticated user.
Mitigation strategies must focus on reinforcing the authorization checks within the Elastic Cloud Enterprise codebase. Developers should implement strict role-based access control verification at every endpoint or function that modifies platform-level settings, ensuring that only users with explicit administrative privileges can execute these operations. It is essential to perform server-side validation of permissions rather than relying solely on client-side restrictions, which are easily bypassed. Additionally, implementing comprehensive audit logging for all configuration changes, regardless of the user's role, will aid in detecting such unauthorized modifications post-exploitation. Organizations should also consider applying principle of least privilege more rigorously across their identity management systems and regularly reviewing access control lists to ensure they accurately reflect current security requirements. Regular penetration testing focused on authorization bypasses can help identify similar weaknesses before they are exploited by malicious actors.
