CVE-2026-84706: 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
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.

CWE-184: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
The affected technology mentions containers, so container-specific ATT&CK technique review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
