CVE-2026-78412 · Severity: medium · CVSS 4.9 · Published 2026-10-05

Velociraptor is a digital forensics and incident response platform that supports multi-tenant deployments with separate organizations. A permissions bug in the WatchEvent gRPC API allows an authenticated user with API access in one organization to read live events from other organizations they should not have access to, potentially exposing sensitive forensic data and investigation details.

## Technical details

The WatchEvent gRPC API accepts an OrgId parameter specifying which organization's events to stream, but the server validates the caller's permissions against their own organization rather than the requested organization. An authenticated attacker can specify a different OrgId to read events from organizations for which they lack authorization, bypassing the intended multi-tenant isolation.
