Nango before 0.71.3 contains an sql injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL by supplying a crafted task group key to the orchestrator API. Attackers can send a malicious group.key to POST /v1/immediate, which TaskEventsHandler.notify() interpolates into a Postgres NOTIFY statement, running stacked queries against the scheduler database.
