RabbitMQ amqp091-go: Connection Configuration Overwrite via Unsanitized TLS Path Parameter Injection

Summary A query parameter injection vulnerability exists in the AMQP client's connection URI formatting logic. When generating or parsing connection URIs, TLS-related filesystem paths such as certificates or keys are appended directly to the URI's query string using string concatenation rather th...

RabbitMQ amqp091-go: Denial of Service via Sub-Spec Frame Size Negotiation

Summary A Denial of Service DoS vulnerability exists in the AMQP client's connection negotiation logic. The AMQP specification explicitly mandates a strict minimum frame size of 4096 bytes to prevent pathological packet fragmentation. While the library defines a frameMinSize = 4096 constant, the...

RabbitMQ Java client has frame-level OOM: Math.min(maxInboundMessageBodySize, 0) defeats frame size enforcement

Vulnerability In AMQConnection.java line 435-436, after Connection.Tune negotiation, the frame-max limit is set via: java frameHandler.setFrameMax Math.minthis.maxInboundMessageBodySize, frameMax; When frameMax = 0 meaning "unlimited" per AMQP spec, Math.min67108864, 0 = 0. This value is then...

CVE-2026-77403

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. A malicious or compromised AMQP broker can exploit this by advertising an extremely small frame size during connection negotiation. This can lead to excessive fragmentation of client publications, consuming significant CPU resources...

CVE-2026-44236: Heap-based Buffer Overflow

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.framemax value during amqplogin, and rabbitmq-c accepts the value in amqplogininner in librabbitmq/amqpsocket.c. amqptuneconnection in...

CVE-2026-44235: Out-of-bounds Read

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized HEADER or METHOD frame during client login and cause unsigned sizet underflow in amqphandleinput in librabbitmq/amqpconnection.c. The parser subtracts HEADERSIZE, fixed...
