# Trigger.dev: SQL injection in query compiler exposes other tenants' data

Trigger.dev before 4.5.6 concatenates window-function names into generated ClickHouse SQL without allowlisting or escaping. An authenticated customer can send a backtick-quoted identifier to the query API and read other organizations' analytics data.

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

## How to check

- Check the installed Trigger.dev version: `unknown` for the exact package name and lockfile path, but confirm whether the version is below `4.5.6`
- Check whether the POST /api/v1/query endpoint is reachable by customer accounts on your deployment

## Fix

- Upgrade Trigger.dev to `4.5.6` or later
- Until upgraded, restrict access to the query endpoint: unknown for a specific workaround in the sources

## From the sources

Trigger.dev before 4.5.6 contains an SQL injection vulnerability in the TSQL query compiler, which concatenates window-function names into generated ClickHouse SQL without allowlisting or escaping. Authenticated customers can submit a backtick-quoted identifier to POST /api/v1/query that injects a raw subquery outside the per-tenant WHERE guard, exfiltrating other organizations' analytics data.
