CVE-2026-22743 PUBLISHED

Server-Side Request Forgery via Filter Expression Keys in Neo4jVectorStore

Assigner: vmware
Reserved: 09.01.2026 Published: 27.03.2026 Updated: 27.03.2026

Spring AI's spring-ai-neo4j-store contains a Cypher injection vulnerability in Neo4jVectorFilterExpressionConverter. When a user-controlled string is passed as a filter expression key in Neo4jVectorFilterExpressionConverter of spring-ai-neo4j-store, doKey() embeds the key into a backtick-delimited Cypher property accessor (node.metadata.) after stripping only double quotes, without escaping embedded backticks.This issue affects Spring AI: from 1.0.0 before 1.0.5, from 1.1.0 before 1.1.4.
