CVE-2026-22743Network attack vector

Server-side request forgery via unescaped filter keys

Published Mar 27, 2026 · Updated Mar 27, 2026

Cypher injection in Spring AI 1.0.0 through 1.0.4 and 1.1.0 through 1.1.3 allows remote attackers to trigger server-side requests. Neo4jVectorFilterExpressionConverter.doKey() strips double quotes but leaves embedded backticks before inserting a filter key into a backtick-delimited Cypher property accessor. Exploitation requires an application path that passes an attacker-controlled filter-expression key to the Neo4j vector store; the vendor does not identify the Neo4j procedure or request destination reached.
