What is CVE-2026-22743?

The spring-ai-neo4j-store component in Spring AI has a vulnerability that arises from improper handling of user-supplied strings. Specifically, the Neo4jVectorFilterExpressionConverter fails to escape embedded backticks when embedding filter keys into Cypher property accessors. This oversight allows attackers to inject malicious Cypher code via user-controlled filter expressions, potentially leading to unauthorized data access or manipulation.
