Elasticsearch 8.19 Support: Frequently Asked Questions
Is the Elasticsearch 8.19 still supported?
Yes. The Elasticsearch 8.19 is currently supported by Elasticsearch, and third-party support is available as an alternative — issue management, vulnerability remediation, and compliance help independent of the vendor contract.
When is the Elasticsearch 8.19 end of service life (EOSL) date?
Elasticsearch lists the end of service life for the Elasticsearch 8.19 as Jul 15, 2027.
Can I keep using the Elasticsearch 8.19 after its EOSL date?
Yes. EOSL means Elasticsearch stops issuing patches and support — the software itself keeps running. Third-party support covers it from there: issue management, security vulnerability remediation, and the compliance documentation auditors ask for, for as long as you choose to run it.
How much does third-party support for the Elasticsearch 8.19 cost?
Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location. You get an indicative price within 24 hours and a firm quote within 48.

| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2026-72649 | HIGH | 8.8 | Sep 1, 2026 | Deserialization of Untrusted Data (CWE-502) in the Elasticsearch machine learning component can lead to remote code execution via Object Injection (CAPEC-586). A specially crafted trained model artifact could cause attacker-controlled logic to execute with a materially broader system-call surface than intended. Exploitation requires an authenticated user with sufficient privileges to create and deploy trained models. |
| CVE-2026-72642 | HIGH | 8.8 | Aug 13, 2026 | The native inference process that Elasticsearch uses to evaluate uploaded machine learning models accepts a model operation that computes a memory address from an offset supplied inside the model, without validating that the offset stays within the bounds of the underlying storage. A user with the privileges required to upload and deploy a trained model can craft a model that reads and writes memory outside the intended allocation. The result is heap corruption that crashes the inference process |
| CVE-2026-103007 | HIGH | 7.2 | Oct 6, 2026 | Incorrect Authorization (CWE-863) in Elasticsearch can lead to Privilege Escalation via a delegated administrative privilege whose scope is not fully enforced during authorization checks. Elasticsearch contains an incorrect authorization weakness in a configurable, non-default privilege that lets an administrator delegate limited role-management capability to another user, scoped to specific indices. The authorization check that enforces this scoping does not correctly account for a role-definit |
| CVE-2026-103009 | HIGH | 7.1 | Oct 6, 2026 | Authorization Bypass Through User-Controlled Key (CWE-639) in Elasticsearch can lead to Information Disclosure via a specially crafted cross-cluster search request that references an unauthorized shard identifier. Elasticsearch contains an authorization bypass weakness in its handling of cross-cluster search requests made through the Remote Cluster Security (RCS) 2.0 model. An authorization check validates a request against one identifying attribute of the target shard, while a separate, indepen |
| CVE-2025-37731 | MEDIUM | 6.8 | Dec 15, 2025 | Improper Authentication in Elasticsearch PKI realm can lead to user impersonation via specially crafted client certificates. A malicious actor would need to have such a crafted client certificate signed by a legitimate, trusted Certificate Authority. |
| CVE-2026-103008 | MEDIUM | 6.5 | Oct 6, 2026 | Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to Denial of Service via a specially crafted request that causes the server to construct and process a deeply nested data structure with no bound on recursion depth. Elasticsearch contains an uncontrolled recursion weakness in how it builds and serializes geometry values produced by scripted runtime fields. Unlike geometry supplied as text, which is subject to a nesting-depth limit, geometry constructed from a script's output is not boun |
| CVE-2026-103006 | MEDIUM | 6.5 | Oct 6, 2026 | Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to Denial of Service via a specially crafted, deeply nested request submitted to the aggregation feature of the search API. Elasticsearch contains an uncontrolled recursion weakness in its search aggregation processing. An authenticated user with read access to a single index can submit a specially crafted request containing deeply nested aggregation definitions. Processing this request triggers unbounded recursive execution that exhaust |
| CVE-2026-103005 | MEDIUM | 6.5 | Oct 6, 2026 | Memory Allocation with Excessive Size Value (CWE-789) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with connector management privileges could cause the cluster to allocate an uncontrolled amount of memory when connector resources with an excessively large `description` field are created and subsequently accessed, exhausting available heap memory and crashing the affected node. |
| CVE-2026-102411 | MEDIUM | 6.5 | Oct 6, 2026 | Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can lead to Denial of Service via Excessive Allocation (CAPEC-130). Elasticsearch enforces a size limit on the user-supplied metadata field for each individual template resource, but does not limit the total memory used when multiple such resources are retrieved together. A user holding the *manage_index_templates* cluster privilege can register multiple resources each within the individual limit. Retrieving them tog |
| CVE-2026-102404 | MEDIUM | 6.5 | Oct 6, 2026 | Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). A low-privileged authenticated user can submit a specially crafted query that causes uncontrolled memory growth in the query processing engine, resulting in an out-of-memory condition that terminates the Elasticsearch node. The condition can be triggered repeatedly, including by queries embedded in shared resources, causing persistent cluster unavailability. |
| CVE-2026-94399 | MEDIUM | 6.5 | Sep 26, 2026 | Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead denial of service via Excessive Allocation (CAPEC-130) |
| CVE-2026-94398 | MEDIUM | 6.5 | Sep 26, 2026 | Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead denial of service via Excessive Allocation (CAPEC-130) |
| CVE-2026-94397 | MEDIUM | 6.5 | Sep 26, 2026 | Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead denial of service via Excessive Allocation (CAPEC-130) |
| CVE-2026-82300 | MEDIUM | 6.5 | Sep 26, 2026 | Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). |
| CVE-2026-82294 | MEDIUM | 6.5 | Sep 26, 2026 | Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). |
| CVE-2026-72687 | MEDIUM | 6.5 | Aug 13, 2026 | A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single small request containing a forged opaque identifier. Elasticsearch decodes and deserializes the identifier before confirming that it was legitimately issued by the cluster, and a size value carried inside the identifier drives an allocation that is neither capped nor accounted for by the available memory-usage controls. The resulting out-of-memory condition is fatal and terminates the affected node process, res |
| CVE-2026-72686 | MEDIUM | 6.5 | Aug 13, 2026 | A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single request containing a crafted user-supplied input. A specific internal component validates the input using a recursive routine and applies no bound to the length of the value being validated, so the validation causes the thread to exhaust its stack. The resulting fatal error is not handled by the surrounding execution paths and terminates the affected node process, producing a denial of service. |
| CVE-2026-72684 | MEDIUM | 6.5 | Aug 13, 2026 | A flaw in Elasticsearch allows an authenticated user holding only read privileges to submit a small search request containing a crafted user-supplied input. Processing that input causes a specific internal component to allocate memory without any upper bound, and the allocation occurs outside the scope of the existing memory accounting controls that were intended to constrain it. The resulting out-of-memory condition is fatal and terminates the affected node process, causing a denial of service. |
| CVE-2026-72683 | MEDIUM | 6.5 | Aug 13, 2026 | A flaw in Elasticsearch allows an authenticated user with the privileges required to invoke the simulate pipeline API endpoint (https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-ingest-simulate) to submit a request that causes a self-referential data structure to be created. When a specific internal component later processes that structure, the operation recurses without bound and raises a fatal error that is not handled by the surrounding execution path, terminating the affe |
| CVE-2026-72679 | MEDIUM | 6.5 | Aug 13, 2026 | Elasticsearch does not apply its configurable input length restriction to a user-supplied pattern accepted by an intervals query. Compiling a deeply nested pattern drives unbounded recursion that exhausts the thread stack and raises a fatal error, terminating the Elasticsearch node process and causing a denial of service for that node. An authenticated user holding only read-only privileges on a single searchable index can trigger the condition with one small search request. |
