CVE-2025-12147Network attack vector

Authenticated data disclosure via queryable excluded object members

Published Oct 29, 2025 · Updated Oct 29, 2025

Information disclosure in Search Guard FLX 3.1.1 and earlier allows remote authenticated users to read FLS-protected object fields. An FLS exclusion removes an object from _source but leaves its child attributes addressable by search queries. Exploitation requires query access and an exclusion on an object-valued field; exposed child values can reconstruct the excluded object.
