CVE-2026-46591Public exploitNetwork attack vector

Cypher injection via unvalidated property names

Published Jul 6, 2026 · Updated Jul 6, 2026

Cypher injection in the Apache Camel Neo4J component allows remote attackers to read, modify, or delete graph data via crafted property names. Neo4jProducer.retrieveNodes() and deleteNode() concatenate keys from CamelNeo4jMatchProperties into Cypher WHERE clauses without validation. Reachability requires a route that carries untrusted data into the match map; the default HTTP header filter blocks direct external submission of the Camel-prefixed header.
