What is CVE-2026-38093?
CVE-2026-38093 is a low-severity path traversal vulnerability in n/a, published on 28 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
file_picker (aka flutter_file_picker) for Flutter, all versions through 10.3.10, is vulnerable to path traversal (CWE-22) in its Android implementation. The openFileStream() method in FileUtils.kt uses the DISPLAY_NAME obtained from ContentResolver.query() directly in file path construction without sanitization. A malicious Android app with a crafted ContentProvider can return a filename containing ../ sequences, causing the plugin to create arbitrary files and directories outside the intended cache directory within the victim app's internal storage. Existing files are not overwritten due to an existence check.
Weakness: CWE-22
