Description Marian Rehak 2021-05-18 11:51:11 UTC
RabbitMQ all versions prior to 3.8.16 are prone to a denial of service vulnerability due to improper input validation in AMQP 1.0 client connection endpoint. A malicious can exploit the vulnerability by sending malicious AMQP messages to the target RabbitMQ instance having the AMQP 1.0 plugin enabled.

All versions of Ansible Tower that used RabbitMQ (Tower versions 3.6 and earlier) are now EOL.

Comment 3 Tapas Jena 2021-05-20 05:14:17 UTC
Hi, marking this as "Not affected" for Ansible Tower as RabbitMQ is no more relevant to Tower Or AAP.
