Combining local files and remote content in a WebView can blur trust boundaries. Restrict file settings to actual needs.
Evaluation approach
Prevent uncontrolled content from accessing local resources. Assess JavaScript, file access and native bridges together.
Application example
A remote help page must not read private application files. Use a separate, limited route for local document viewing.
Limits and considerations
Trust in one domain does not extend automatically to every embedded resource or redirect.
Why separate local and remote content?
A local document viewer and remote help page need not share configuration. Disabling unnecessary privileges per flow makes review easier. One exceptional screen should not weaken defaults throughout the application.
Checks and decisions
- Limit local access
- Review bridges
- Test redirects
