{"cve":"CVE-2026-106121","nvd":{"published":"2026-10-06T19:17:43.193","modified":"2026-10-09T18:26:02.737","status":"Analyzed","description":"The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.37.0, com.rabbitmq.tools.json.JSONReader.read() fails to terminate when input ends inside a quoted string or a line comment because its string and whitespace scanners do not stop at CharacterIterator.DONE. The default DefaultJsonRpcMapper passes JSON-RPC message bodies to this parser for JsonRpcServer and client replies. A truncated string causes the parser to append replacement end markers until heap exhaustion, while a line comment without a terminating newline can keep a thread consuming CPU indefinitely, resulting in denial of service. This issue is fixed in version 5.37.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-835"],"references":["https://github.com/rabbitmq/rabbitmq-java-client/commit/25fad817291feff3195c32620117d295598f8b41","https://github.com/rabbitmq/rabbitmq-java-client/pull/2100","https://github.com/rabbitmq/rabbitmq-java-client/releases/tag/v5.37.0","https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-cqgh-8p3p-mx4m","https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-cqgh-8p3p-mx4m"],"products":["vmware:rabbitmq_java_client"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-106121","score":0.00533,"percentile":0.4472,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cqgh-8p3p-mx4m","url":"https://osv.dev/vulnerability/GHSA-cqgh-8p3p-mx4m","summary":"RabbitMQ: JSONReader in the default JSON-RPC mapper never terminates on truncated input, causing DoS","modified":"2026-10-07T21:00:04.481305005Z","packages":[{"ecosystem":"Maven","name":"com.rabbitmq:amqp-client","purl":"pkg:maven/com.rabbitmq/amqp-client","ranges":["<5.36.1"],"fixed":["5.36.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
