Summary
Spring AI has a Cypher Injection vulnerability in Neo4jVectorFilterExpressionConverter
Details

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.
