CVE-2026-97720— Apache Impala: Impala Executor Webserver Auth Bypass

Quick assessment

Affected
Apache Software Foundation Apache Impala
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.

在 Apache Impala 4.5.2 及更早版本的 Impala 执行器（executors）中，JWT/OAuth 身份验证的实现存在缺陷，攻击者可利用此漏洞访问由执行器的 Web 服务器提供的资源，前提是该 Web 服务器已配置为接受 JWT/OAuth 令牌。由于未对 Bearer 令牌（JWT）签名进行验证，导致 Web 服务器接受任何合法的 JWT 令牌。 建议用户要么为 Impala 执行器禁用 JWT/OAuth 身份验证，要么升级到修复此问题的 4.5.3 版本。

Vulnerability Title
Apache Impala: Impala Executor Webserver Auth Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect implementation of JWT/OAuth authentication in Impala executors in Apache Impala versions up to and including 4.5.2 which allows attacked to access resources served by the executor's webserver when that webserver is configured to accept JWT/OAuth tokens.  Bearer token (JWT) signatures are not validated resulting in the webserver accepting any valid JWT. Users are recommended to either disable JWT/OAuth auth for Impala executors or upgrade to version 4.5.3, which fixes this issue.
