{"cve":"CVE-2026-106122","nvd":{"published":"2026-10-06T19:17:43.467","modified":"2026-10-09T18:21:32.203","status":"Analyzed","description":"The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.36.0, ValueReader.readShortstr decodes malformed UTF-8 bytes into replacement characters that can re-encode beyond the AMQP shortstr limit enforced by ValueWriter.writeShortstr. An attacker who can submit an RPC message with a malformed echoed property can cause reply publication in RpcServer.mainloop() or tutorial-style consumers to throw an unchecked exception before acknowledgement. The broker requeues the message, allowing the same message to disable replacement consumers until the queue is purged. This issue is fixed in version 5.36.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.0},"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-172","CWE-248"],"references":["https://github.com/rabbitmq/rabbitmq-java-client/commit/b8bd750fa8c90690e859b18d6343b34421309020","https://github.com/rabbitmq/rabbitmq-java-client/pull/2065","https://github.com/rabbitmq/rabbitmq-java-client/releases/tag/v5.36.0","https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-7822-rcf6-97fx","https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-7822-rcf6-97fx"],"products":["vmware:rabbitmq_java_client"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-106122","score":0.00491,"percentile":0.41925,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7822-rcf6-97fx","url":"https://osv.dev/vulnerability/GHSA-7822-rcf6-97fx","summary":"RabbitMQ: Malformed UTF-8 in shortstr properties permanently disables RPC consumers","modified":"2026-10-07T20:30:07.156315722Z","packages":[{"ecosystem":"Maven","name":"com.rabbitmq:amqp-client","purl":"pkg:maven/com.rabbitmq/amqp-client","ranges":["<5.36.0"],"fixed":["5.36.0"]}]}],"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).
