### Official description

A flaw was found in Ansible Tower, versions 3.6.x before 3.6.2 and 3.5.x before 3.5.3, where enabling RabbitMQ manager by setting it with '-e rabbitmq_enable_manager=true' exposes the RabbitMQ management interface publicly, as expected.

Check this codebase for CVE-2019-19340 and fix it if it is affected.

What it is: CVE-2019-19340 is a high-severity vulnerability in Redhat Ansible Tower, published on 19 Dec 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-19340 in the wild and no public exploit code.

Affected product: Redhat Ansible Tower. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
