Short explanation

iFlytek Astron Agent through versions 1.1.2 contains an insecure direct object reference vulnerability that allows bypassing authorization via the POST /workflow/v1/resume endpoint and breaches cross-tenant isolation.

Why does it matter?

This vulnerability allows authenticated applications to interfere with paused workflows of other applications and read continuation output streams, compromising corporate data privacy and cross-tenant isolation.

What should be done?

  • Follow official vendor advisories
  • Review authorization checks on application workflow endpoints
  • Apply access restrictions until patch status is verified

Show the technical text from the sources

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.
