CVE-2026-0532
Description
A flaw was found in Kibana. This vulnerability allows an authenticated attacker, with privileges to create or modify connectors, to disclose arbitrary files. The attacker achieves this by submitting a specially crafted configuration for the Google Gemini connector, which the server processes without proper validation, enabling arbitrary network requests and file reads.
Statement
This vulnerability is rated Important for Red Hat products as it allows an authenticated attacker with privileges to create or modify connectors in Kibana to disclose arbitrary files. Exploitation requires a specially crafted configuration for the Google Gemini connector. Red Hat products like Enterprise Application Platform, OpenShift Container Platform, Red Hat OpenStack Platform, and Red Hat OpenShift distributed tracing that include Kibana are affected.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Integrity
Technical Impact: Execute Unauthorized Code or Commands
Access Control
Technical Impact: Bypass Protection Mechanism
By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
