Summary
Jitsu console before 2.14.0-beta.41 from jitsucom contains an incorrect authorization flaw (CWE-863) in the sources/state.ts handlers, which call findFirst without await, so the syncId ownership check never fails. An authenticated user who knows another workspace's sync ID can read, overwrite or delete that workspace's stream cursors, which can cause data to be ingested again or skipped.
