CVE-2026-56144— Incorrect Authorization in Elasticsearch Leading to Information Disclosure

Quick assessment

Affected
Elastic Elasticsearch
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.

Elastic Elasticsearch是荷兰Elastic公司开源的一个搜索分析引擎。 Elastic Elasticsearch 9.4.0至9.4.3版本、9.0.0至9.3.6版本和8.12.0至8.19.17版本存在授权问题漏洞，该漏洞源于授权不当，可能导致经过身份验证且具有有限索引特权的用户利用摄取模拟功能中不充分的授权控制，通过针对其无权直接访问的索引，执行并返回这些索引配置的摄取管道的输出，从而披露这些管道处理或丰富的数据，并可检索索引映射元数据。

Vulnerability Title
Incorrect Authorization in Elasticsearch Leading to Information Disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect Authorization (CWE-863) in Elasticsearch can allow an authenticated user with limited index privileges to exploit insufficient authorization controls in the ingest simulation feature. By targeting indices they are not authorized to access directly, the user can cause those indices' configured ingest pipelines to execute and return their output, potentially disclosing data processed or enriched by those pipelines. Additionally, the same feature can be used to retrieve index mapping metadata for indices the user are not authorized to access directly.
