Summary
mcp-neo4j-cypher: SSRF and Data Modification via read_only Mode Bypass Through CALL Procedures
Details

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.
