# Velociraptor: flawed SQL plugin lets queries read server files

Link for people: https://infrastack.ai/live/CVE-2026-85737 (this .md is for agents)

The SQL plugin in Velociraptor opens outbound database connections without the file-read and network permission checks. A rogue MySQL server can make the Velociraptor server read files it can access, including root-readable files when it runs as root.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the Velociraptor server version is below `0.77.2`.
- Check whether the server process runs as root.
- Check which users hold `ANY_QUERY` permission.

## Fix

- Velociraptor: move to `0.77.2` or later.

## From the sources

Velociraptor is a tool for collecting host-based state information using Velociraptor Query Language (VQL) queries. Prior to 0.77.2, SQLPlugin.Call in vql/parsers/sql/sql.go does not enforce plugin-level FILESYSTEM_READ or NETWORK checks before the mysql and postgres branches pass a caller-controlled connstring to sql.Open, allowing arbitrary outbound database connections. With attacker-controlled MySQL connection options that enable local-infile access, a rogue MySQL server can request files readable by the Velociraptor server process, including root-readable files when that process runs as root. The SQLite file accessor still enforces FILESYSTEM_READ, but a low-privilege analyst with ANY_QUERY can use the zero-permission data accessor and ATTACH DATABASE to create files without the plugin-level check. This issue is fixed in version 0.77.2.
