ecosystem impact- 3 maven packages depend on com.rabbitmq:amqp-client (2 direct, 1 indirect)
Ecosystem-wide dependent count for version 5.33.1.
DescriptionCVE.org
The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. 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.

AnalysisAI
Memory exhaustion denial of service in the RabbitMQ Java client library (com.rabbitmq:amqp-client ≤ 5.33.0) allows a malicious AMQP peer to crash the client JVM by sending a LongString field with a wire-declared length near Integer.MAX_VALUE during the pre-authentication connection.start handshake. The ValueReader.readBytes() method allocates a byte array sized by the attacker-controlled wire value before validating it against actual frame data, causing a ~2 GB allocation and OutOfMemoryError that terminates the entire JVM process. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim Java application to initiate an outbound AMQP connection to an endpoint controlled or compromised by the attacker, as the malicious payload is delivered server-to-client during the connection.start pre-authentication handshake - no client-side configuration change is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.7 with vector AV:N/AC:L/AT:N/PR:N/UI:N/VA:H accurately reflects the technical severity: remote, unauthenticated denial of service exploitable in the pre-authentication phase with no special attack prerequisites on the protocol level. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker deploys a malicious AMQP-compatible server at a network endpoint reachable by victim Java applications and waits for a client connection. When the victim client connects, the malicious server responds to the AMQP connection.start handshake with a server-properties table containing a LongString field (type tag 0x53) with a wire-declared length of 0x7FFFFFFE. … |
| Remediation | Upgrade the com.rabbitmq:amqp-client Maven dependency to version 5.33.1 or later, which is the vendor-released patch confirming the fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
