CVE-2026-6290 Rapid7 CVE debrief

Who should care

Defenders and administrators of Velociraptor systems should assess exposure and verify user access controls to mitigate the risk of unauthorized data access or lateral movement. They should also review Velociraptor versions, monitor for suspicious activity, and implement compensating controls if necessary.

Why it matters

CVE-2026-6290 allows authenticated Velociraptor users to access and query data in other orgs they are not authorized to access, potentially leading to unauthorized data access or lateral movement within the environment. Defenders should verify Velociraptor versions, review user access controls, and monitor for suspicious activity.

• Potential unauthorized access to sensitive data in other orgs
• Possible lateral movement within Velociraptor environments
• Need for verification of user access controls and permissions
• Potential for data tampering or unauthorized queries

Technical summary

The query() plugin in Velociraptor versions prior to 0.76.3 allows an authenticated GUI user with access in one org to run VQL queries on other orgs they may not have access to, using the same permissions as in the org containing the notebook. This can lead to unauthorized data access or lateral movement within the environment. Defenders should prioritize verifying Velociraptor versions and user access controls to mitigate this vulnerability. The vulnerability is due to insufficient access control in the query() plugin, which allows users to execute VQL queries across different orgs.

Defensive priority

Defenders should prioritize verifying Velociraptor versions and user access controls.

Recommended defensive actions

• Verify Velociraptor version and upgrade to 0.76.3 or later
• Review user access controls and permissions
• Monitor for suspicious activity in Velociraptor notebooks
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but additional verification is needed to determine the full scope of affected systems and users. Velociraptor versions prior to 0.76.3 are affected, and defenders should verify Velociraptor versions, review user access controls, and monitor for suspicious activity in Velociraptor notebooks.
