CVE-2026-46591

/// Technical description

Improper Neutralization of Special Elements in Data Query Logic vulnerability in Apache Camel Neo4J component.

The camel-neo4j producer builds the Cypher WHERE clause for its match/retrieve and delete operations from the CamelNeo4jMatchProperties map. CVE-2025-66169 addressed Cypher injection through the property values by binding them as query parameters ($paramN), but the property names (the JSON keys of that map) were still concatenated into the query string verbatim in Neo4jProducer.retrieveNodes() and deleteNode(). A property name containing Cypher syntax therefore alters the structure of the executed query. Where a route maps untrusted input into the CamelNeo4jMatchProperties map - for example by passing a request body as the match map, or from a consumer that does not filter inbound Camel* headers - an attacker who controls the JSON key names can inject arbitrary Cypher and read, modify or delete any node or relationship in the Neo4j database.
