CVE-2026-43973 affecting package rabbitmq-server for versions less than 3.13.7-6

CVE-2026-43973 affecting package rabbitmq-server for versions less than 3.13.7-6. A patched version of the package is available...

rabbitmq-server: RabbitMQ: Information Disclosure via Cross-Site Scripting in Federation Management

A flaw was found in the RabbitMQ rabbitmqfederationmanagement plugin. This cross-site scripting XSS vulnerability occurs because the consumertag field on the Federation Status page does not properly escape HTML. A user with permissions to configure a federation upstream or policy can exploit this...

rabbitmq: RabbitMQ: Authentication bypass allows remote connection for loopback-restricted users via incorrect loopback check

A flaw was found in RabbitMQ, a messaging and streaming broker. The AMQP 0-9-1, AMQP 1.0, and Stream Protocol authentication mechanisms incorrectly perform a loopback check. This allows a user, typically restricted to loopback connections such as a guest user, to connect remotely. This occurs whe...

RabbitMQ: RabbitMQ: Information disclosure via authorization bypass in AMQP 0-9-1 operations

A flaw was found in RabbitMQ. This vulnerability allows an authenticated user, with the ability to connect to a virtual host, to bypass authorization checks during passive queue.declare and exchange.declare AMQP 0-9-1 Advanced Message Queuing Protocol operations. This bypass enables the user to...

RabbitMQ: RabbitMQ: Persistent foreign bindings allow unauthorized message routing

A flaw was found in RabbitMQ, a messaging and streaming broker. This vulnerability allows an attacker to establish persistent foreign bindings to reply-to destinations. This occurs because temporary queues are not properly removed, leaving behind active routing entries. This can lead to...

rabbitmq: RabbitMQ: Authorization bypass allows unauthorized topic writes and binds during metadata-store failures

A flaw was found in RabbitMQ, a messaging and streaming broker. During metadata-store failures, the topic authorization mechanism can incorrectly allow restricted topic writes and binds. This occurs because permission lookup errors from Khepri are treated as an 'allow' condition by the internal...

rabbitmq-server: RabbitMQ: Denial of Service via oversized JSON bodies in HTTP API

A flaw was found in RabbitMQ, a messaging and streaming broker. A remote attacker could exploit this vulnerability by sending oversized JSON bodies to the rabbitmqmanagement HTTP API. The API's body size check is incomplete, allowing the final combined size to exceed limits. This could lead to a...

rabbitmq-server: RabbitMQ: Information disclosure due to improper consumer reauthorization

A flaw was found in RabbitMQ. An existing consumer in RabbitMQ AMQP 0-9-1 can continue to receive messages even after its OAuth token has expired or its connection's scopes have been reduced. This occurs because consumers are not properly canceled or reauthorized when the channel user state...

rabbitmq: RabbitMQ: Information disclosure via path validation bypass in management plugin

A flaw was found in RabbitMQ. The RabbitMQ management plugin static file handler, rabbitmgmtwmstatic, on Windows can be exploited when multiple management extension plugins are enabled. An attacker can pass specially crafted URL-encoded backslashes, bypassing path validation. This can lead to...

RabbitMQ: RabbitMQ: Cross-site Scripting in management UI allows arbitrary JavaScript execution

A flaw was found in RabbitMQ, a messaging and streaming broker. The RabbitMQ management user interface UI improperly handles the x-internal-purpose argument when rendering queue or exchange details. This vulnerability allows a user with permissions to declare a queue or exchange to inject and...

RabbitMQ: RabbitMQ: OAuth 2 client secret disclosure via obsolete API endpoint

A flaw was found in RabbitMQ, a messaging and streaming broker. An unauthenticated remote attacker could exploit an obsolete API endpoint GET /api/auth to disclose the OAuth 2 client secret. This vulnerability occurs when the RabbitMQ management plugin and OAuth configuration are enabled, leading...
