CVE-2026-77406

A flaw was found in RabbitMQ amqp091-go. The Channel.Qos function in channel.go incorrectly handles negative integer values for prefetchCount and prefetchSize, casting them to large unsigned integers. This allows an application that processes untrusted Quality of Service QoS configuration to...

CVE-2026-77409

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. When the client synchronously sends events to application-provided channels, an unbuffered or full listener channel can cause the client's reader to block. This blockage prevents the processing of critical messages and heartbeats,...

CVE-2026-77410

A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send an extreme declared message body size to a client. This causes the client to attempt an excessively large memory allocation without proper size capping, leading to memory exhaustion and termination of the client...

CVE-2026-77404

A flaw was found in RabbitMQ amqp091-go. The URI.String function in uri.go concatenates TLS asset path values directly into an AMQPS query string without proper encoding. If an application processes a TLS asset path containing special characters like ampersand or equals delimiters, these can be...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the amqplogin process when an undersized connection.tune.framemax value is accepted and used to reallocate the outbound buffer without enforcing minimum size constraints. An attacker can cause memory...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the amqphandleinput function. An attacker can cause a process crash and out-of-bounds read by sending a specially crafted AMQP frame during client login, resulting in a denial of service. This can be triggered by ...

CVE-2026-44236

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...
