Security readout for executives and security teams
Plain-English summary
CVE-2019-7614 is a race condition in Elasticsearch that could cause one user to receive sensitive response header data belonging to another user. The issue affects Elasticsearch versions before 7.2.1 and 6.8.2. Business urgency depends on whether older Elasticsearch clusters serve multiple users or tenants.
Executive priority
Prioritize remediation for internet-facing, shared, or multi-tenant Elasticsearch clusters. Lower urgency may apply to isolated single-user deployments, but unsupported or old versions should still be upgraded.
Technical view
Elastic describes a CWE-362 race condition in response header handling. On systems with multiple users submitting requests, an attacker could gain access to a response header containing sensitive data from another user. The CVE record lists affected Elasticsearch versions as before 7.2.1 and 6.8.2.
Likely exposure
Exposure is most relevant for Elasticsearch deployments older than 7.2.1 or 6.8.2, especially shared clusters or services where multiple users make requests concurrently.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not listed as KEV. Exploitation requires a multi-user request environment and successful triggering of a race condition that leaks another user’s response header.
Researcher notes
Public data is limited: no CVSS score is provided in the source bundle, and no exploit status is cited. The key technical condition is a response-header race condition under concurrent multi-user request patterns.
Mitigation direction
- Upgrade Elasticsearch to 7.2.1, 6.8.2, or a later supported version.
- Review Elastic security guidance for any environment-specific recommendations.
- Reduce shared access to vulnerable clusters until upgraded.
- Assess whether sensitive data is present in response headers.
Validation and detection
- Inventory Elasticsearch versions across all clusters.
- Confirm no production cluster runs versions before 7.2.1 or 6.8.2.
- Identify multi-user or tenant-shared Elasticsearch deployments.
- Review logs and architecture for exposure of sensitive response headers.

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
