Elastic has disclosed a crucial vulnerability in its Elastic Cloud Enterprise (ECE) platform that permits directors with malicious intent to execute arbitrary instructions and exfiltrate delicate knowledge.
Tracked as CVE-2025-37729 below advisory ESA-2025-21, the flaw stems from improper neutralization of particular components within the Jinjava template engine.
This challenge impacts a number of variations of ECE, probably exposing enterprise environments to extreme dangers if exploited by insiders or compromised admin accounts.
The vulnerability arises when specifically crafted strings containing Jinjava variables are evaluated through the processing of deployment plans within the ECE admin console.
Attackers with admin privileges can inject malicious payloads into these plans, resulting in code execution. The outcomes of such executions can then be learn again by means of ingested logs, enabling knowledge theft or additional system compromise.
Elastic emphasizes that exploitation requires entry to the admin console and a deployment with the Logging+Metrics characteristic enabled, narrowing the menace vector to privileged customers however amplifying the affect in shared or multi-tenant setups.
Elastic Cloud Enterprise Vulnerability
This flaw impacts ECE variations from 2.5.0 as much as and together with 3.8.1, in addition to variations 4.0.0 by means of 4.0.1.
Organizations working these builds in manufacturing face heightened publicity, significantly these leveraging ECE for scalable cloud administration in logging and metrics workloads.
The CVSS v3.1 rating of 9.1 underscores its criticality, with a vector of AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H, indicating community accessibility, low complexity, excessive privileges required, however scope change enabling excessive confidentiality, integrity, and availability impacts.
Whereas no proof-of-concept exploits have been publicly launched, the advisory particulars how attackers may craft payloads like these mimicking interpreter instructions.
As an example, injecting strings that consider Jinjava expressions may set off distant code execution, much like template injection assaults seen in different platforms.
Elastic notes that the problem doesn’t have an effect on standalone Elastic Stack elements however is particular to ECE’s enterprise deployment orchestration.
Mitigations
Elastic urges rapid upgrades to patched variations 3.8.2 or 4.0.2, which tackle the neutralization flaw within the template engine.
For these unable to patch promptly, no direct workarounds exist, although organizations can restrict admin console entry by means of strict role-based controls and monitoring.
To detect potential exploitation, Elastic recommends scanning request logs with the question: (payload.title : int3rpr3t3r or payload.title : forPath). This will flag suspicious exercise indicative of injected payloads.

As enterprises more and more depend on ECE for hybrid cloud observability, this vulnerability highlights the necessity for vigilant privilege administration.
Elastic’s speedy disclosure permits proactive protection, however delayed patching may invite insider threats or lateral motion in breached networks.
