Low risk16th percentile - higher than 16% of all known CVEs
Summary
Authorization Bypass Through a User-Controlled Key (CWE-639) in Elastic Cloud Enterprise (ECE) can lead to privilege escalation. An attacker who controls any host in an ECE installation can obtain credentials reserved for other platform roles.
Risk Assessment
The obtained credentials can give the attacker full control of the ECE control plane and the deployments it manages.
Recommendation
Update ECE to a patched version and verify credential isolation between platform roles.
Other vulnerabilities in Elastic Cloud Enterprise
See all- CVE-2025-37729Critical
Improper neutralization of special elements in the template engine of Elastic Cloud Enterprise (ECE) allows an admin-level actor to exfiltrate sensitive information and issue commands via a specially crafted string where Jinjava variables are evaluated.
- CVE-2026-115713High
Improper Link Resolution Before File Access (CWE-59) in Elastic Cloud Enterprise (ECE) allows a symlink attack (CAPEC-132). This can lead to unauthorized read and write access to data of other deployments on the same host.
- CVE-2026-115712Medium
Incorrect Authorization (CWE-863) in Elastic Cloud Enterprise (ECE) allows an authenticated user with read-only access to change an installation-wide account setting that only platform administrators should be permitted to change.
- CVE-2026-115711Medium
Insertion of Sensitive Information into an Externally-Accessible File or Directory (CWE-538) in Elastic Cloud Enterprise (ECE) can lead to credential disclosure. ECE stores runtime information about platform service containers in a location readable by lower-privileged components, and this data includes secrets from container configuration, including role tokens.
- CVE-2026-115709High
Improper Link Resolution Before File Access (CWE-59) in Elastic Cloud Enterprise (ECE) allows a symlink attack (CAPEC-132). This can lead to unauthorized disclosure and loss of data belonging to other deployments on the same host.
- CVE-2026-115708High
Improper Link Resolution Before File Access (CWE-59) in Elastic Cloud Enterprise (ECE) allows a symlink attack (CAPEC-132). This can lead to authentication bypass and unauthorized changes to the configuration of other deployments on the same host.
- CVE-2026-115707Medium
Insertion of Sensitive Information into an Externally-Accessible File or Directory (CWE-538) in Elastic Cloud Enterprise (ECE) can lead to privilege escalation. After the ECE certificate rotation procedure runs, retained data contains platform credentials and certificate authority private keys readable by lower-privileged components.
- CVE-2025-37736High
Improper Authorization in Elastic Cloud Enterprise can lead to Privilege Escalation where the built-in readonly user can call APIs that should not be allowed. The affected APIs include operations on service accounts, users, and API keys.
Original NVD description (English source)
Authorization Bypass Through User-Controlled Key (CWE-639) in Elastic Cloud Enterprise (ECE) can lead to privilege escalation via Privilege Abuse (CAPEC-122). An attacker who controls any host in an ECE installation can obtain credentials that are reserved for other platform roles. These credentials can give the attacker full control of the ECE control plane and of the deployments that it manages.
