DescriptionA 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.
