Jitsu Console Authorization Flaw Allows Sync ID Abuse

Publication date: 2026-10-22

Last updated on: 2026-10-22

Assigner: VulnCheck

Description

Jitsu console before 2.14.0-beta.41 contains an incorrect authorization vulnerability in sources/state.ts handlers that call findFirst without await, so the syncId ownership check never fails. Authenticated users knowing another workspace's sync ID can read, overwrite or delete its stream cursors, causing data re-ingestion or skipped data.
