**Description** def _escape(v: str) -> str: return str(v).replace("'", "\\'").replace("\\", "\\\\") The escaping order is backwards, exactly like the classic HTML double-escape bug: step 1 inserts a literal backslash in front of every ', then step 2 re-matches that just-inserted backslash and doubles it. For an input ending in a single quote, the two steps combined produce \\' (two backslashes followed by the quote) in the output — which, under the standard backslash-escape convention used by Cypher/openCypher single-quoted string literals, is parsed as one escaped backslash followed by an unescaped, string-terminating quote. The quote is not neutralized; the string breaks open. This escaped value is interpolated directly into Cypher query strings built by string formatting (not parameters) at 5 call sites in the same method: self.lc_graph.query( f"MERGE (n: {{id: '{_escape(node.id)}'}}) " f"{props}" f"RETURN distinct 'done' AS result" ) ... self.lc_graph.query( f"MATCH (a: {{id: '{_escape(rel.source.id)}'}}), " f"(b: {{id: '{_escape(rel.target.id)}'}}) " f"MERGE (a)-[r: ]->(b) " f"{props}" f"RETURN distinct 'done' AS result" ) node.type, rel.source.type, rel.target.type and rel_type are also interpolated into backtick-quoted identifiers with no escaping at all. Where the attacker-controlled data comes from: node/rel objects are LLM-extracted entities and relationships derived from ingested document content (the whole point of this GraphRAG pipeline). Document content is therefore untrusted input relative to this database layer — a classic indirect-prompt-injection-to-query-injection chain: craft a document whose text causes the extraction LLM to produce an entity id containing the payload below, ingest it, and the broken escape function turns it into live Cypher. **Impact** Full Cypher clause injection into lc_graph.query() calls that run with no query parameterization and no read-only restriction visible in this adapter. Demonstrated impact: appending a second cla

    Detected

    Flexible GraphRAG is a Python framework for building graph and retrieval-augmented generation applications across multiple graph, vector, and search backends. From 0.6.0 until 0.8.2, the _escape() helper in flexible-graphrag/langchain/graph/pg_store_adapters/falkordb_adapter.py escapes quotes before backslashes and then interpolates the result into Cypher assembled by FalkorDBAdapter.add_graph_doc
