Impact

The file names constructed within file_selector are missing sanitization checks leaving them vulnerable to malicious document providers.

This may result in cases where a user with a malicious document provider installed can select a document file from that provider while using your app and could potentially override internal files in your app cache.

Patches

0.5.1+12

Workarounds

Update to the latest version of file_selector_android that contains the changes to address this vulnerability.
