## Overview

A flaw was found in the automation-controller input-validation
                  guard sanitize_jinja(). The function uses two regular
                  expressions to reject user-supplied Jinja, but the patterns
                  stop at the first interior '}' or '%' character, so a Jinja
                  expression containing an inner brace (for example an empty
                  dict) is accepted while remaining valid Jinja. Because
                  sanitize_jinja() is the sole guard on several launch-time
                  fields — ad-hoc command module_args, Machine-credential
                  username / become_method / become_user, and inventory host
                  names — a low-privileged user can inject Jinja that ansible-core
                  evaluates in the execution environment. This enables execution
                  of arbitrary commands in the execution environment (bypassing an
                  administrator's AD_HOC_COMMANDS module allowlist) and disclosure
                  of secrets belonging to credentials the attacker cannot read
                  (by templating a co-attached credential's injected environment
                  variables), across the credential access-control boundary.
