Elasticsearch 8.x < 8.19.20 / 9.0.x < 9.4.5 Multiple Vulnerabilities (ESA-2026-76 / ESA-2026-77 / ESA-2026-118 / ESA-2026-119 / ESA-2026-133)

The version of Elasticsearch installed on the remote host is 8.x prior to 8.19.20, or 9.0.x prior to 9.4.5. It is, therefore, affected by multiple vulnerabilities as referenced in the ESA-2026-76, ESA-2026-77, ESA-2026-118, ESA-2026-119, and ESA-2026-133 advisories. - Uncontrolled Recursion CWE-6...

Uncontrolled Recursion

com.rabbitmq, amqp-client is vulnerable to Uncontrolled Recursion. The vulnerability is due to ValueReader.readTable and ValueReader.readArray recursively processing nested AMQP table and array values without a nesting-depth limit, which allows an attacker controlling the AMQP server or network...

BIT-ELASTICSEARCH-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...

BIT-ELASTICSEARCH-2026-72683 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

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...

BIT-ELASTICSEARCH-2026-72679 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

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...

BIT-ELASTICSEARCH-2026-72647 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

Uncontrolled Recursion CWE-674 in Elasticsearch can lead to denial of service via Serialized Data with Nested Payloads CAPEC-230.

RabbitMQ Java client ValueReader: Unbounded recursive table/array nesting causes StackOverflowError DoS

Summary ValueReader.readTable and readArray recursively call readFieldValue with no depth limit. A malicious AMQP peer can crash the client JVM by sending a deeply nested table structure.

CVE-2026-72647

A flaw was found in Elasticsearch. An authenticated user with read privileges on a single index can submit a specially crafted search request. This request, containing deeply nested serialized data, is processed without a depth limit, leading to uncontrolled recursion. This can exhaust the thread...

CVE-2026-69220: Uncontrolled Recursion
