CVE-2026-84707
Description
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
Statement
This flaw affects automation-controller as shipped in Red Hat Ansible Automation Platform. Exploitation requires an authenticated user with at least the Read role on one inventory whose hosts have been targeted by jobs; the impact is disclosure of job and ad-hoc command output -- which may contain plaintext secrets -- for jobs the user has no permission to view, including across organizations, without any ability to modify data. Cross-organization disclosure of tenant data is a tenancy crossing under a single controller authorization authority and does not change the CVSS scope. Red Hat recommends both marking event_data and stdout as non-searchable and restricting host_filter to an allow-list of host-local fields rather than permitting open ORM relation traversal.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
Access control checks for specific user data or functionality can be bypassed.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Horizontal escalation of privilege is possible (one user can view/modify information of another user).
Access Control
Technical Impact: Gain Privileges or Assume Identity
Vertical escalation of privilege is possible if the user-controlled key is actually a flag that indicates administrator status, allowing the attacker to gain administrative access.
