Mobasi Research

This Sentinel update covers a second Velociraptor vulnerability, which became public on October 5, 2026. Rapid7 published it as CVE-2026-78412.

Velociraptor

One Velociraptor server can hold many orgs. Each org keeps its own endpoints, users, and data. Teams that support more than one client often put each client in a different org.

Cross-Org Event Read via the WatchEvent API

medium
Issue
The WatchEvent gRPC API lets the caller name the org to stream events from. The server checked permissions against the caller's own org, not the requested org.
Impact
A user with API access in one org can read live events from another org on the same server, with no access to that org.
Advisory
CVE-2026-78412

Rapid7 fixed the issue in Velociraptor v0.77.3, released October 5, 2026. Update to v0.77.3 or later.
