Technical details
The API file upload mechanism fails to correctly bind uploaded files to the authenticating user's identity, instead reusing the same session token for all token-based API callers. An attacker with knowledge of another user's API token could theoretically access files uploaded by that user via the API. Mitigation is inherent: uploaded files exist only for 24 hours and are referenced by random UUIDs, making exploitation difficult in practice.
