CVE-2026-115293— Insertion of Sensitive Information Into Sent Data in Kibana Leading to Credential Disclosure

Quick assessment

Affected
Elastic Kibana
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Kibana Observability 的入站配置中存在“向发送数据中插入敏感信息”漏洞（CWE-201），可能导致 Kibana 用于连接 Elasticsearch 的凭证泄露。当这些凭证被嵌入到 Kibana 配置中的 Elasticsearch 主机 URL 时，拥有入站 Observability 数据权限的已认证用户即可获取这些凭证。随后，该用户便可直接以 Kibana 服务账户的权限访问 Elasticsearch，而该权限超出了该用户原本被授予的权限范围。

Vulnerability Title
Insertion of Sensitive Information Into Sent Data in Kibana Leading to Credential Disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
Insertion of Sensitive Information Into Sent Data (CWE-201) in Kibana Observability onboarding can lead to disclosure of the credentials that Kibana uses to connect to Elasticsearch. When these credentials are embedded in the Elasticsearch host URLs in the Kibana configuration, an authenticated user with the privileges to onboard Observability data can obtain them. The user can then access Elasticsearch directly with the privileges of the Kibana service account, which are outside the privileges granted to that user.
