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.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
