CVE-2026-41274: CWE-943: Improper Neutralization of Special Elements in Data Query Logic in FlowiseAI Flowise
Flowise versions prior to 3. 1. 0 contain a critical vulnerability (CVE-2026-41274) in the GraphCypherQAChain node, where user input is directly passed into the Cypher query execution pipeline without proper sanitization. This allows attackers to inject arbitrary Cypher commands, potentially leading to unauthorized data exfiltration, modification, or deletion on the underlying Neo4j database. The vulnerability is fixed in version 3. 1. 0. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-41274 is a critical injection vulnerability in FlowiseAI's Flowise product affecting versions before 3.1.0. The GraphCypherQAChain node fails to properly neutralize special elements in user-supplied input before forwarding it to the Neo4j Cypher query execution pipeline. This improper neutralization (CWE-943) enables attackers to execute arbitrary Cypher commands on the database, risking data confidentiality, integrity, and availability. The issue is resolved in Flowise version 3.1.0.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary Cypher queries on the Neo4j database used by Flowise, which can lead to data exfiltration, unauthorized data modification, or deletion. This compromises the confidentiality, integrity, and availability of the database. The CVSS 4.0 base score is 9.3 (critical), reflecting the high impact and ease of exploitation without privileges or user interaction.
Mitigation Recommendations
Upgrade Flowise to version 3.1.0 or later, where this vulnerability is fixed. Since this is a self-hosted product, users must apply the update themselves. Patch status is confirmed fixed in 3.1.0. No other mitigations are indicated by the vendor advisory.
