CVE-2024-7042Public exploit

Graph data manipulation via prompt-injected Cypher queries

Published Oct 29, 2024 · Updated Oct 15, 2025

SQL injection in LangChain.js before 0.3.1 allows attackers to manipulate graph data through prompt injection in GraphCypherQAChain. The class passes model-generated Cypher derived from a user-influenced question to the configured graph query operation without restricting it to read-only statements. Exploitation requires an application to use this chain with attacker-controlled prompts, and resulting data access, modification, deletion, or interruption is bounded by the graph credentials.
