This can cause the reporting service to send network requests to destinations that should be blocked by security policies.
AI Analysis
Technical Summary
This vulnerability (CWE-863) in Elastic Kibana arises from an incomplete list of disallowed inputs (CWE-184) in the Reporting feature. An authenticated attacker with Reporting access can circumvent configured outbound request restrictions, leading the reporting service to send requests to unauthorized network destinations. The issue affects specific Kibana versions 8.0.0, 9.0.0, and 9.4.0. There is no vendor-provided remediation or patch information available at this time.
Potential Impact
An attacker with authenticated access to the Reporting feature can bypass network request restrictions, potentially causing Kibana to send requests to unauthorized or restricted network destinations. This could lead to unintended data exposure or network policy violations. The confidentiality impact is low, with no integrity or availability impacts reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the Reporting feature to trusted users only and monitor for suspicious activity related to outbound requests from Kibana.
