Summary

Gokapi has Data Leak in Upload Status Stream

Details

Description

The upload status SSE implementation on /uploadStatus publishes global upload state to any authenticated listener and includes file_id values that are not scoped to the requesting user.

Impact

Any authenticated user can observe other users' file identifiers and retrieve unauthorized content, causing cross-tenant data exposure and loss of confidentiality for uploaded documents.
