- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

CVE-2026-85737 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.5 (medium) and affects velociraptor; fixed in 0.77.2.

## Summary

Velociraptor, a tool for collecting host state information, lets a remote attacker with a low-privilege analyst account read arbitrary files on the server, including root-readable files when the server runs as root. The attacker reaches it over the network with low-privilege login and no user interaction, by abusing the unchecked `sql()` plugin to make outbound database connections to a rogue MySQL server that requests local files.

## Affected

- Velocidex velociraptor: fixed in 0.77.2

## Description

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.
