Official description

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.
