Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java uses ValueReader.readBytes to accept a wire-declared contentLength below Integer.MAX_VALUE and allocate a byte array before checking the bytes available in the frame. A malicious AMQP peer can send a LongString or byte-array field with type tag S and a declared length such as 0x7FFFFFFE during the pre-authentication connection.start server-properties table, causing an approximately 2 GB allocation and OutOfMemoryError before readFully consumes data. The resulting memory exhaustion can terminate the JVM and cause denial of service. This issue is fixed in version 5.33.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-789"],"references":["https://github.com/rabbitmq/rabbitmq-java-client/commit/388209356c6478088efce4d8a07b68e73837a7a0","https://github.com/rabbitmq/rabbitmq-java-client/commit/6a87a8dcdc8b4cc4b961a7cdd388276446e5dfb2","https://github.com/rabbitmq/rabbitmq-java-client/pull/2007","https://github.com/rabbitmq/rabbitmq-java-client/pull/2008","https://github.com/rabbitmq/rabbitmq-java-client/releases/tag/v5.33.1"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-69219","score":0.00725,"percentile":0.5379,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-68mj-5wr7-6fgg","url":"https://osv.dev/vulnerability/GHSA-68mj-5wr7-6fgg","summary":"RabbitMQ Java client ValueReader: Oversized LongString/bytes length triggers OOM via unchecked allocation","modified":"2026-09-10T03:51:13.151154373Z","packages":[{"ecosystem":"Maven","name":"com.rabbitmq:amqp-client","purl":"pkg:maven/com.rabbitmq/amqp-client","ranges":["<5.33.1"],"fixed":["5.33.1"]}]}],"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).
