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."

Cuando se pasa una cadena controlada por el usuario como clave de expresión de filtro en ’Neo4jVectorFilterExpressionConverter’ de ’spring-ai-neo4j-store’, ’doKey()’ incrusta la clave en un accesor de propiedad Cypher delimitado por comillas invertidas (node.’metadata.’) después de eliminar solo las comillas dobles, sin escapar las comillas invertidas incrustadas.
