CVE-2026-53561— Apache Hive: Unauthenticated authentication bypass in HiveServer2 HTTP SAML bearer-token validation allows impersonation of any Hive user

Quick assessment

Affected
Apache Software Foundation Apache Hive
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.

Apache Hive是美国Apache基金会的一款数据仓库基础架构软件。 Apache Hive 4.0.0版本至4.2.0版本存在安全漏洞，该漏洞源于HiveServer2 SAML bearer-token验证不当，可能导致未经身份验证的网络攻击者通过向/cliservice HTTP端点发送伪造的Authorization: Bearer token，以任意Hive用户身份进行认证并获得经过认证的HiveServer2会话。

Vulnerability Title
Apache Hive: Unauthenticated authentication bypass in HiveServer2 HTTP SAML bearer-token validation allows impersonation of any Hive user
Source: CVE Program / CVE List V5
Vulnerability Description
An improper authentication vulnerability in HiveServer2 SAML bearer-token validation in Apache Hive 4.0.0 through 4.2.0 (and later unreleased branches) on deployments using HTTP transport with hive.server2.authentication=SAML allows an unauthenticated network attacker to authenticate as an arbitrary Hive user and obtain an authenticated HiveServer2 session via a forged Authorization: Bearer token sent to the /cliservice HTTP endpoint. Users are recommended to upgrade to 4.2.1 version that includes the fix for this issue. Access / authorization required: No Hive credentials, SAML IdP login, or knowledge of the server signing secret is required. The attacker only needs network reachability to the HiveServer2 HTTP port (typically /cliservice), directly or through a reverse proxy such as Apache Knox that forwards unauthenticated requests to HS2. The instance must have SAML authentication enabled in HTTP mode. Deployments where Knox handles SSO and HiveServer2 uses LDAP/Kerberos (not native SAML mode) are not affected by this specific issue.
