Velociraptor verify() VQL Function Artifact Overwrite

Publication date: 2026-08-24

Last updated on: 2026-08-24

Assigner: Rapid7, Inc.

Description
The Velociraptor verify() VQL function allows a user to verify an artifact for syntatic and other issues. Due to an implementation fault in this VQL function, the global artifact repository is used which allows callers to overwrite existing artifacts without the required permissions.  The attacker need only have the NOTEBOOK_EDIT permission (e.g. an analyst role) to be able to call this function.

Executive Summary

CVE-2026-19200 is a flaw in Velociraptor's verify() VQL function that allows users with NOTEBOOK_EDIT permission to overwrite existing artifacts in the global repository without proper authorization. This occurs due to missing authorization checks and improper code generation control, enabling potential code injection.

Detection Guidance

To detect this vulnerability, check Velociraptor logs for unauthorized artifact modifications or suspicious use of the verify() VQL function by users with NOTEBOOK_EDIT permission. Review artifact repository changes and compare versions before and after potential exploitation.

Impact Analysis

An attacker with NOTEBOOK_EDIT permission could overwrite built-in artifacts, leading to unauthorized code execution or data manipulation. This could compromise system integrity, confidentiality, and availability, especially if sensitive artifacts are targeted.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality principles or HIPAA's safeguards for protected health information. Non-compliance risks include legal penalties and reputational damage.

Mitigation Strategies

Upgrade Velociraptor to version 0.77.2 or later to apply the security fix. Restrict NOTEBOOK_EDIT permissions to trusted users only. Monitor artifact repository changes and audit logs for suspicious activity.
