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."}], "lastModified": "2026-10-09T18:26:02.737", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:vmware:rabbitmq_java_client:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DA24C4A3-F79F-400D-9CC8-9886341BA95C", "versionEndExcluding": "5.37.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
