Summary
iFlytek Astron Agent through 1.1.2 contains an insecure direct object reference vulnerability that allows authenticated applications to resume other applications' paused workflows by supplying their event_id to POST /workflow/v1/resume. Attackers can predict Snowflake event IDs to inject resume content into victim workflows and read their continuation output stream, breaking cross-tenant isolation.
