A flaw was found in Red Hat Ansible Automation Platform's automation-controller.
The host_filter query parameter on the hosts list API is parsed into a raw Django
ORM filter whose lookup path is validated only against a sensitive-field blocklist,
with no authorization check on the database relations it traverses. Because job
event and ad-hoc command output fields are not on that blocklist, an authenticated
user holding only the Read role on an inventory can construct filters that traverse
into the output of jobs they have no permission to view and use the returned host
count as a boolean oracle. Using regular-expression lookups, the attacker can
extract, character by character, the output (which routinely contains plaintext
credentials, tokens, and command results) of jobs and ad-hoc commands belonging to
other organizations, resulting in cross-tenant disclosure of job output
