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'.

Public PoC Released for Apache Superset SQL Injection Vulnerability

A public Python PoC exploit is available for CVE-2026-23980, an authenticated error-based SQL injection in Apache Superset versions before 6.0.0.

CVE-2026-23980 is a SQL injection flaw (CWE-89) in Apache Superset affecting all releases before 6.0.0, exploitable via the sqlExpression and where parameters by authenticated users with read-level access. A public repository containing a Python exploit.py proof-of-concept has been released, reducing attacker effort against exposed instances. Apache disclosed the issue on February 24, 2026 and fixed it in Superset 6.0.0. Defenders should upgrade and monitor logs for malformed queries, database errors, and unusual activity from low-privilege accounts.
