AI Threat Summary

CVE-2026-115707 is a moderate vulnerability with a CVSS score of 6.4 affecting elastic_cloud_enterprise, elastic_cloud_enterprise. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.

Description

Insertion of Sensitive Information into Externally-Accessible File or Directory (CWE-538) in Elastic Cloud Enterprise (ECE) can lead to privilege escalation via Retrieve Embedded Sensitive Data (CAPEC-37). After the ECE certificate rotation procedure runs, data that it retains contains platform credentials and certificate authority private keys, and lower-privileged platform components can read this data. An attacker who controls any host in the installation can use this data to get full control of the ECE control plane and of the deployments that it manages.

Attack Chain
1
Initial Access

Attacker has low-privilege local access (e.g., via phishing or compromised service account)

2
Privilege Escalation

Attacker exploits CVE-2026-115707 to escalate from low-privilege user to root/SYSTEM/admin

3
Defense Evasion

Elevated privileges used to disable security controls, clear logs, and establish persistence

4
Impact

Full system compromise achieved; attacker can install ransomware, exfiltrate all data, or pivot

MITRE ATT&CK Techniques
T1068 Exploitation for Privilege Escalation
Privilege Escalation

Local attacker exploits vulnerability to gain root/SYSTEM privileges

T1134 Access Token Manipulation
Privilege Escalation

Elevated token used to impersonate high-privilege accounts
