CVE-2026-41274
CriticalSummary
Flowise prior to version 3.1.0 has a vulnerability in the GraphCypherQAChain node that forwards user-provided input without proper sanitization. This allows an attacker to inject arbitrary Cypher commands that are executed on the Neo4j database.
Risk Assessment
An attacker can gain access to data, modify it, or delete it, posing a serious threat to the integrity and confidentiality of data within the organization.
Recommendation
It is recommended to upgrade to version 3.1.0 or later to mitigate this vulnerability and implement additional security measures to protect the database.

Original NVD description (English source)
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the GraphCypherQAChain node forwards user-provided input directly into the Cypher query execution pipeline without proper sanitization. An attacker can inject arbitrary Cypher commands that are executed on the underlying Neo4j database, enabling data exfiltration, modification, or deletion. This vulnerability is fixed in 3.1.0.
