CVE-2026-57866: Apache Impala: Secrets Exfiltration via SSRF

Apache Impala CVE-2026-57866 lets authenticated users abuse ai_generate_text() to exfiltrate secrets from configured Hadoop credential providers via SSRF.

A server-side request forgery affects Apache Impala versions 4.4.0 through 4.5.1. Authenticated users with permission to execute the ai_generate_text() function can exfiltrate secrets provided by credential providers configured via hadoop.security.credential.provider.path in core-site.xml. The attacker must know the secret's key name, and Apache rates the issue 'important'.

CVE-2026-54048: Apache Impala: Avro Schema URL Server-Side Request Forgery

Apache Impala CVE-2026-54048 lets crafted Avro schema URLs trigger SSRF to internal endpoints, with responses potentially leaking via error messages.

A server-side request forgery in Apache Impala 2.0.0 through 4.5.1 on all platforms can be triggered via an Avro schema URL using an http or file:/// URI on a table. An attacker can cause Impala to send GET requests to internal endpoints it can access, and responses may be exposed through parsing error messages. Users are advised to upgrade to a fixed release.
