DescriptionNVD

mcp-neo4j-cypher is an MCP server for executing Cypher queries against Neo4j databases. In versions prior to 0.6.0, the read_only mode enforcement can be bypassed using APOC CALL procedures, potentially allowing unauthorized write operations or server-side request forgery. This issue is fixed in version 0.6.0.

AnalysisAI

mcp-neo4j-cypher before version 0.6.0 allows authenticated users to bypass read-only mode enforcement via APOC CALL procedures, enabling unauthorized write operations and server-side request forgery against Neo4j databases. The vulnerability requires login credentials and attacker preparation (CVSS AT:P), limiting real-world risk to insider threats or compromised accounts with legitimate access to the MCP server.
