CVE-2026-84706: Red Hat Ansible Automation Platform automation-controller credential type injection

CVE-2026-84706 · Severity: high · CVSS 7.6 · Published 2026-09-23

A flaw in Ansible Automation Platform's automation-controller allows privileged users to inject environment variables that bypass security restrictions. An attacker can write malicious scripts and use loader variables like BASH_ENV to execute arbitrary code within job execution environments, compromising the security of automated workflows.

Vendors: Red Hat.

Technical details

The custom Credential Type environment-variable injector uses an incomplete deny-list (checking only ANSIBLE_* prefix and a fixed ENV_BLOCKLIST) that fails to block process-hijacking loader variables such as BASH_ENV, ENV, LD_PRELOAD, LD_LIBRARY_PATH, PYTHONSTARTUP, and GIT_SSH_COMMAND. A privileged user can combine this with the credential file injector to write attacker-controlled scripts into the execution environment and point BASH_ENV at it, achieving arbitrary code execution inside the execution-environment container.
