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-2026-72684

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...

CVE-2026-72687

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-2026-72678

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-2026-72679

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-2026-72683

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. Whe...

CVE-2026-72672

The Elastic Security capability that suggests existing field values while a user authors endpoint policy artifacts queries Elastic Defend event data with Kibana's internal Elasticsearch account instead of the account of the requesting user. Only Kibana feature privileges are verified, and the...

CVE-2026-72656

Memory Allocation with Excessive Size Value CWE-789 in the ES|QL query processing of Elasticsearch can lead to denial of service via Excessive Allocation CAPEC-130. An authenticated user able to submit ES|QL queries could send a specially crafted query whose evaluation allocates an unbounded amou...

CVE-2026-72647

Uncontrolled Recursion CWE-674 in Elasticsearch can lead to denial of service via Serialized Data with Nested Payloads CAPEC-230. An authenticated user holding only read privileges on a single index can submit one specially crafted search request whose deeply nested structure is processed without...

CVE-2026-72639

Elasticsearch does not enforce an upper bound on a user-supplied count accepted by a search highlighting option, and the allocation derived from that count is not accounted against any circuit breaker. An authenticated user holding only read privileges on a single searchable index can submit one...

CVE-2026-72638

Uncontrolled Recursion CWE-674 in Elasticsearch can lead to denial of service via Input Data Manipulation CAPEC-153. An authenticated user holding only low-privileged index creation permissions can submit a single request containing a specially crafted, malformed custom analysis definition that i...

CVE-2026-72642

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 th...

CVE-2026-72645

Memory Allocation with Excessive Size Value CWE-789 in Elasticsearch can lead to denial of service via Excessive Allocation CAPEC-130. An authenticated user holding only read privileges on a single index can submit one small, specially crafted search request that causes an excessively large memor...

CVE-2026-72636

Uncontrolled Recursion CWE-674 in the Elasticsearch wildcard matching helper can lead to a denial of service via Excessive Allocation CAPEC-130. The matcher used to resolve wildcard patterns against names is implemented recursively and had no bound on recursion depth or on the total number of mat...

CVE-2026-72631

Improper Privilege Management CWE-269 in Kibana Fleet can lead to privilege escalation via Privilege Escalation CAPEC-233. An integration policy may optionally declare extra data streams that the integration writes to, which Fleet adds to the Elasticsearch API key issued to Elastic Agents enrolle...
