What is CVE-2026-22729?

A JSONPath injection vulnerability exists in Spring AI's AbstractFilterExpressionConverter, which allows authenticated users to bypass access controls through maliciously crafted filter expressions. This flaw arises when user-supplied inputs to the FilterExpressionBuilder are not escaped properly, enabling the injection of arbitrary JSONPath logic. Attackers can exploit this weakness to access unauthorized documents by manipulating the input in a way that alters the intended logic of the JSONPath queries. This risk is particularly pronounced in applications utilizing vector stores for multi-tenant isolation, role-based access control, or metadata-driven document filtering.
