Exposing the Android file system to WebViews is security-sensitive. Granting file access to WebViews, particularly through the `file://` scheme, introduces a risk of local file inclusion vulnerabilities. The severity of this risk depends heavily on the specific `WebSettings` configured. Overly permissive settings can allow malicious scripts to access a wide range of local files, potentially exposing sensitive data such as Personally Identifiable Information (PII) or private application data, leading to data breaches and other security compromises.
