Описание

Origin

This vulnerability was identified by Team RabbitMQ and/or other teams at Broadcom, not via a responsible disclosure from an external researcher.

Description

validate_partitions only checks that the requested partition count is at least 1, with no upper bound. A large count such as lists:seq(0, 500000000) allocates roughly 8GB.

Preconditions

The rabbitmq_stream_management plugin must be enabled. The caller needs the management tag and access to the target vhost.
