Technical Analysis
CVE-2026-72670 is a vulnerability in Kibana where users with limited privileges (read access to agent policies) can access the full configuration of a Fleet proxy. This access bypasses intended privilege restrictions that normally require Fleet-specific privileges to read such settings. The exposed proxy configuration can contain sensitive information such as proxy authentication credentials and private keys, which should not be accessible to lower privileged users.
Potential Impact
Unauthorized disclosure of sensitive Fleet proxy credentials and private key material to users without appropriate privileges, potentially compromising proxy security and confidentiality of authentication data.
Mitigation Recommendations
A patch is available for this vulnerability. Users should apply the official fix to affected Kibana versions to prevent unauthorized access to Fleet proxy configurations.
