Spring AI Filter Expression Injection

A critical SQL injection vulnerability in Spring AI's MariaDBFilterExpressionConverter component allows authenticated attackers to bypass metadata-based access controls and execute arbitrary SQL commands due to missing input sanitization. VMware Spring AI versions 1.0.x prior to 1.0.4 and 1.1.x prior to 1.1.3 are affected. With a CVSS score of 8.8, this vulnerability enables attackers with low-level privileges to compromise confidentiality, integrity, and availability of the database system through network-based attacks with low complexity.

Spring AI's AbstractFilterExpressionConverter fails to properly escape user-controlled input in JSONPath queries, allowing authenticated attackers to inject arbitrary expressions and bypass access controls in vector store implementations. This impacts applications relying on the converter for multi-tenant isolation, role-based access, or metadata-based document filtering, enabling attackers to access unauthorized documents. No patch is currently available.
