An attacker could exploit this by checking the `www_authenticate_uri parameter` (which is visible to all end users) in configuration files. This would give sensitive information which may aid in additional system exploitation. A patch is available on the `master` branch and anticipated to be part of version 11.6.1.\n\n## Affected packages\n\n- `tripleo-heat-templates < 11.6.1`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `tripleo-heat-templates 11.6.1`","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
