CVE-2026-115706: Elastic Cloud Enterprise authorization bypass leading to privilege escalation

CVE-2026-115706 · Severity: medium · CVSS 6.8 · Published 2026-10-29

Elastic Cloud Enterprise (ECE) is a platform that manages and controls Elasticsearch deployments in private environments. An attacker with administrative access to any host in an ECE installation can exploit an authorization bypass vulnerability to obtain credentials for other roles and gain full control over the entire ECE control plane and all managed deployments. This could allow an attacker to read, modify, or delete all data and systems managed by ECE.

Technologies: Elastic Cloud Enterprise. Vendors: Elastic.

Technical details

Authorization bypass through user-controlled key (CWE-639) in ECE allows privilege escalation via privilege abuse (CAPEC-122). An attacker who controls a host in the ECE installation, including hosts running only the allocator role, or who has network access to internal ECE platform services, can obtain credentials reserved for other platform roles. The vulnerability grants attackers full control of the ECE control plane and managed deployments.
