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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"rabbitmq","product":"rabbitmq-java-client","versions":[{"version":"\u003c 5.36.1","status":"affected"}]},{"vendor":"com.rabbitmq","product":"amqp-client","versions":[{"version":"\u003c 5.36.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","baseScore":4.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.2,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-06T18:32:40.985871Z","id":"CVE-2026-106121","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-835"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:vmware:rabbitmq_java_client:*:*:*:*:*:*:*:*","versionEndExcluding":"5.37.0","matchCriteriaId":"DA24C4A3-F79F-400D-9CC8-9886341BA95C"}]}]}],"references":[{"url":"https://github.com/rabbitmq/rabbitmq-java-client/commit/25fad817291feff3195c32620117d295598f8b41","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/rabbitmq/rabbitmq-java-client/pull/2100","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/rabbitmq/rabbitmq-java-client/releases/tag/v5.37.0","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-cqgh-8p3p-mx4m","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-cqgh-8p3p-mx4m","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Vendor Advisory"]}]}}
