CVE-2026-116340 · Severity: medium · CVSS 4.3 · Published 2026-10-26

iFlytek astron-agent is an agentic workflow platform that manages files and knowledge across users. An authenticated user can bypass ownership checks to read knowledge records from files owned by other users by adding a numeric space-id header to requests, gaining unauthorized access to sensitive information.

## Technical details

The FileInfoV2Service.listKnowledgeByPage endpoint skips object-level authorization checks when a client-supplied space-id header is parseable by Long.parseLong(), even if the value differs from the authenticated user's actual space ID. An attacker with a valid Console session JWT can exploit this to read knowledge records from arbitrary files via a simple header manipulation, though the vulnerability is read-only and requires prior knowledge of victim file IDs.
