CVE-2026-0532 Elastic CVE debrief

CVE-2026-0532 is a critical vulnerability that combines External Control of File Name or Path (CWE-73) with Server-Side Request Forgery (CWE-918). This allows an attacker with authenticated access and sufficient privileges to create or modify connectors to cause arbitrary file disclosure through a specially crafted credentials JSON payload in the Google Gemini connector configuration. The vulnerability exists because the server processes configurations without proper validation, enabling arbitrary network requests and file reads. Elastic has acknowledged this issue, and multiple sources, including Red Hat, have provided additional details and patches.

Who should care

Security teams and administrators responsible for Google Gemini connector configurations should prioritize patching this vulnerability. The high CVSS score of 8.6 indicates significant risk, and the nature of the vulnerability suggests that exploitation could lead to sensitive data exposure.

Technical summary

CVE-2026-0532 is a high-severity vulnerability (CVSS score of 8.6) that arises from the combination of CWE-73 and CWE-918 weaknesses in the Google Gemini connector. An attacker with authenticated access and the ability to create or modify connectors can exploit this vulnerability by crafting a malicious credentials JSON payload. This allows for arbitrary file disclosure and network requests. The vulnerability is due to insufficient validation of configurations by the server.

Defensive priority

High priority should be given to patching this vulnerability due to its high CVSS score and the potential for sensitive data exposure. Security teams should ensure that all Google Gemini connector configurations are reviewed and updated to the latest version.

Recommended defensive actions

  • Review and update Google Gemini connector configurations to ensure they are using the patched version.
  • Restrict access to connector creation and modification to only those who require it.
  • Monitor for suspicious activity related to file access and network requests.
  • Implement additional security measures, such as input validation and network request filtering.
  • Consider compensating controls, such as monitoring and exception tracking, until patching can be completed.
