CVE-2026-110764: Authorization Bypass Through User-Controlled Key in iflytek astron-rpa
Description
CVE-2026-110764 is an authorization bypass vulnerability in iflytek astron-rpa versions up to 1.1.6. It allows authenticated users to download files belonging to other tenants by manipulating the fileId parameter in the /file/download endpoint. The vulnerability arises because the FileMapper.getFile method does not verify file ownership or tenant association, enabling enumeration of predictable Snowflake file IDs to access unauthorized S3-stored files.

Technical Analysis
The vulnerability in iflytek astron-rpa (<=1.1.6) is an insecure direct object reference in the resource-service /file/download endpoint. Authenticated users can supply arbitrary fileId values, which are predictable Snowflake IDs, to download files belonging to other tenants. This occurs because the FileMapper.getFile function lacks checks for file ownership or tenant boundaries, leading to unauthorized access to S3-stored files uploaded by different tenants.
Potential Impact
Authenticated users can bypass authorization controls to access files of other tenants, potentially exposing sensitive data stored in S3. This compromises tenant data isolation and confidentiality within the astron-rpa platform. There is no indication of active exploitation in the wild at this time.
Mitigation Recommendations
A patch is available for this vulnerability. Since astron-rpa is a cloud service, the vendor manages remediation server-side. Users should verify with the vendor advisory that their environment is updated to a fixed version beyond 1.1.6 to ensure the vulnerability is addressed.
