CVE-2026-42156: CWE-943: Improper Neutralization of Special Elements in Data Query Logic in reconurge flowsint
Flowsint is an open-source OSINT graph exploration tool designed for cybersecurity investigation, transparency, and verification. Prior to 1.2.3, a remote attacker can create a node with a malicious type that can escape an existing Cypher query and an adversary can execute an arbitrary Cypher query. This vulnerability is fixed in 1.2.3.
AI Analysis
Technical Summary
CVE-2026-42156 is a vulnerability in reconurge's flowsint tool before version 1.2.3, classified under CWE-943 (Improper Neutralization of Special Elements in Data Query Logic). It allows a remote attacker with low privileges to inject a specially crafted node type that escapes the existing Cypher query constraints, enabling arbitrary Cypher query execution. This can compromise the integrity of the graph database queries used by flowsint. The vulnerability is addressed by updating to version 1.2.3.
Potential Impact
An attacker can execute arbitrary Cypher queries remotely without user interaction and with low privileges, potentially leading to unauthorized data access or manipulation within the flowsint graph database environment. This undermines the security and trustworthiness of the OSINT investigations performed using flowsint versions prior to 1.2.3.
Mitigation Recommendations
Upgrade flowsint to version 1.2.3 or later, where this vulnerability is fixed. Since no official patch link or vendor advisory is provided, users should verify the update from the official reconurge sources. Patch status is not yet confirmed by a vendor advisory; check reconurge's official channels for current remediation guidance.
