Technical description

A SQL injection in the flutter_downloader component through 1.11.1 for iOS allows remote attackers to steal session tokens and overwrite arbitrary files inside the app's container. The internal database of the framework is exposed to the local user if an app uses UIFileSharingEnabled and LSSupportsOpeningDocumentsInPlace properties. As a result, local users can obtain the same attack primitives as remote attackers by tampering with the internal database of the framework on the device.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
