CVE-2026-18635: CWE-863 in Rapid7 Velociraptor
CVE-2026-18635 is a vulnerability in Rapid7 Velociraptor prior to version 0.77.2 where the VQL query() plugin incorrectly evaluates the IMPERSONATE permission against the caller's organization instead of the target organization. This flaw allows an administrator in one organization to impersonate a user in another organization without having the proper permission in that target organization.
AI Analysis
Technical Summary
Velociraptor's VQL query() plugin enables running queries in different organizational or user contexts, requiring the caller to have the IMPERSONATE permission. Versions before 0.77.2 incorrectly check this permission against the caller's organization rather than the target organization, allowing cross-org impersonation by administrators who should not have this capability in the target org.
Potential Impact
An administrator in one organization can impersonate users in other organizations where they do not have the IMPERSONATE permission. This can lead to unauthorized access and potentially full control over resources or data in the target organization, impacting confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrative privileges carefully and monitor for suspicious impersonation activities.
