According to the Red Hat advisory, no mitigation is currently available that meets Red Hat Product Security criteria for ease of use, deployment, applicability, or stability. Users should monitor Red Hat's official advisory for updates and apply any future patches or fixes once released. Until then, restrict administrator access and avoid forwarding logs to untrusted external aggregators.

Description

CVE-2026-84691 is a high-severity vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8. It involves an externally-controlled Python format string used in logging API 4XX errors. An authenticated administrator can exploit this to read sensitive application secrets, including the Django SECRET_KEY and database password, by crafting a malicious format string. These secrets are logged and can be forwarded to external log aggregators, potentially exfiltrating them. This enables offline decryption of stored credentials, session forgery, and direct database access.
