automation-controller: automation-controller: CredentialType injector validation renders attacker-supplied Jinja2 templates synchronously in the web worker, allowing uncontrolled resource consumption (denial of service) and an unhandled-exception (500) via /api/controller/v2/credential_types/

A flaw was found in Red Hat Ansible Automation Platform's automation-controller. When a custom credential type is created or updated, the injector configuration is validated by rendering each attacker-supplied Jinja2 template synchronously inside the web request worker, with no limit on iteration...

automation-controller: automation-controller-container: automation-controller: CUSTOM_VENV_PATH setting provides filesystem path-existence oracle on control pod

StringListPathField.tointernalvalue calls os.path.exists on unbounded user-supplied paths. 200 vs 400 response reveals existence of arbitrary absolute paths on the controller-web pod. Tenant superuser can confirm /etc/tower/SECRETKEY, k8s service-account token, receptor sockets, ConfigMap mount...

automation-controller-container: automation-controller: automation-controller: server-side request forgery via the Thycotic Secret Server external credential plugin test endpoint (caller-controlled server_url, backend executed in the controller web process)

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The Thycotic Secret Server external credential plugin passes a user-supplied server URL to its SDK without validating the scheme, host, or IP range, and the plugin backend is executed synchronously within the...
