CVE-2026-84706 (GCVE-0-2026-84706)

Vulnerability from cvelistv5 – Published: 2026-09-23 19:39 – Updated: 2026-09-24 05:58

Title

Automation-controller: automation-controller-container: automation-controller: credential type env-injector deny-list omits process-hijacking variables (bash_env/ld_preload) allowing code execution in the execution environment

Summary

A flaw was found in Ansible Automation Platform's automation-controller. The custom Credential Type environment-variable injector validates variable names against a deny-list (an ANSIBLE_* prefix check plus a fixed ENV_BLOCKLIST) that omits process-hijacking loader variables such as BASH_ENV, ENV, LD_PRELOAD, LD_LIBRARY_PATH, PYTHONSTARTUP and GIT_SSH_COMMAND. Combined with the credential file injector, a privileged user can write an attacker-controlled script into the execution environment and point BASH_ENV at it, obtaining arbitrary code execution inside the execution-environment container for any job that attaches a credential of that type.

Severity

7.6 (High)
