CVE-2026-72672

Summary: CVE-2026-72672 describes an incorrect authorization in Kibana that can disclose Elastic Defend endpoint event data. The root cause is that Elastic Security queries use Kibana’s internal Elasticsearch account, not the requesting user’s account, and only Kibana feature privileges are check...

CVE-2026-72679

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...

CVE-2026-72679

Elasticsearch is affected by CVE-2026-72679 due to a pattern-compiled intervals query that can recurse unboundedly if a deeply nested pattern is supplied. The root cause is that input length restrictions are not applied to user-supplied patterns, allowing an authenticated, read-only user on a sin...

CVE-2026-72678

CVE-2026-72678 : Elasticsearch vulnerability where a user-controlled size value is not validated before memory reservation, enabling memory exhaustion. An authenticated user with read privileges can send a single crafted request to a REST API endpoint, causing the node to attempt an excessively l...

CVE-2026-72678

Elasticsearch does not validate a size value taken from a user-supplied input before that value is used to reserve memory for an internal data structure. An authenticated user holding only read privileges can submit a single small crafted request to a product API endpoint that causes the node to...

CVE-2026-72678 Memory Allocation with Excessive Size Value in Elasticsearch Leading to Denial of Service

Elasticsearch does not validate a size value taken from a user-supplied input before that value is used to reserve memory for an internal data structure. An authenticated user holding only read privileges can submit a single small crafted request to a product API endpoint that causes the node to...

CVE-2026-72687 Memory Allocation with Excessive Size Value in Elasticsearch Leading to Denial of Service

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...

CVE-2026-72687

CVE-2026-72687 describes a memory allocation DoS in Elasticsearch where a low-privileged authenticated user can submit a forged opaque identifier, which is decoded and deserialized before cluster verification, causing an unbounded allocation and node termination. Affected versions span 8.0.0–8.19...

CVE-2026-72686 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

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...

EUVD-2026-58250

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...

CVE-2026-72686

The CVE-2026-72686 issue affects Elasticsearch and causes Denial of Service via uncontrolled recursion in a input-validation recursive routine, exhausting stack and terminating the node process. Affected versions: all 8.0.0–8.19.19 and 9.0.0–9.4.4, plus 9.5.0. Remediation: upgrade to 8.19.20, 9.4...

EUVD-2026-58249

A flaw in Elasticsearch allows a low-privileged authenticated user who can index documents to submit a single small document containing a crafted user-supplied input. Processing one such document occupies a worker thread from a bounded pool for a disproportionate amount of time, degrading the...

CVE-2026-72685

A flaw in Elasticsearch allows a low-privileged authenticated user who can index documents to submit a single small document containing a crafted user-supplied input. Processing one such document occupies a worker thread from a bounded pool for a disproportionate amount of time, degrading the...

CVE-2026-72685 Inefficient Algorithmic Complexity in Elasticsearch Leading to Denial of Service
