Server Side Request Forgery in Apache Impala

Publication date: 2026-09-09

Last updated on: 2026-09-10

Assigner: Apache Software Foundation

Description

Server side request forgery in Apache Impala versions 4.4.x and 4.5.x. Authenticated Impala users with permissions to execute the ai_generate_text() function can exfiltrate secrets provided by the credential providers configured in the `hadoop.security.credential.provider.path` property of `core-site.xml`. The secret's key must be known to the user.

Attack-Flow Graph

Executive Summary

This is a Server Side Request Forgery (SSRF) vulnerability in Apache Impala versions 4.4.0 through 4.5.1. Authenticated users with permission to run the ai_generate_text() function can exfiltrate secrets from credential providers configured in core-site.xml. The attacker must know the secret's key to exploit this.

Detection Guidance

To detect this vulnerability, check Apache Impala versions 4.4.0 through 4.5.1. Verify if the ai_generate_text() function is accessible to authenticated users. Inspect core-site.xml for hadoop.security.credential.provider.path configurations. Monitor network traffic for unusual exfiltration attempts from Impala processes.

Impact Analysis

An attacker with valid Impala credentials could steal sensitive secrets like passwords or API keys stored in the credential provider. This could lead to unauthorized access to systems, data breaches, or further compromise of the environment.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, potentially violating GDPR (data protection) and HIPAA (health information privacy) requirements. Organizations may face compliance violations, fines, or reputational damage if exploited.

Mitigation Strategies

Upgrade Apache Impala to a version beyond 4.5.1. Restrict permissions for the ai_generate_text() function to only necessary users. Review and secure credential provider paths in core-site.xml. Disable or audit any suspicious network access patterns from Impala.
