- Issue
- Graphiti versions before 0.28.2 contained a Cypher injection vulnerability in shared search-filter construction for non-Kuzu backends. Attacker-controlled label values supplied through SearchFilters.nodelabels were concatenated directly into Cypher label expressions without validation. In MCP deployments, this was exploitable not only through direct untrusted access to the Graphiti MCP server, but also through prompt injection against an LLM client that could be induced to call searchnodes with attacker-controlled entitytypes values. The MCP server mapped entitytypes to SearchFilters.nodelabels, which then reached the vulnerable Cypher construction path. Affected backends included Neo4j, FalkorDB, and Neptune. Kuzu was not affected by the label-injection issue because it used parameterized label handling rather than string-interpolated Cypher labels. This issue was mitigated in 0.28.2.

Recommended action: Upgrade to 0.28.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
