CVE-2026-20238Network attack vector

Confidential data access via inherited search-filter override

Published May 20, 2026 · Updated May 20, 2026

Incorrect authorization in Splunk AI Toolkit before 5.7.3 allows remote authenticated users to read data restricted by custom roles. The app's authorize.conf adds srchFilter to the built-in user role, and Splunk joins inherited filters with OR, overriding stricter child-role filters. Accounts must inherit the built-in user role and lack admin or power; affected searches can disclose confidential results but cannot modify data.
