{"id":"CVE-2026-106121","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-106121","generatedAt":"2026-10-28T02:24:00.959Z","title":"The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes.","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.","published":"2026-10-06T19:17:43.000Z","lastModified":"2026-10-09T18:26:03.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-835"],"affected":["vmware/rabbitmq java client"],"epss":{"score":0.00533,"percentile":0.44741,"date":"2026-10-26","history":[{"date":"2026-10-07","score":0.00493,"percentile":0.4036}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%).
