Detailsinfo

A vulnerability, which was classified as problematic, has been found in file_picker Plugin up to 10.3.10. This issue affects the function openFileStream of the file FileUtils.kt of the component Android Implementation. The manipulation of the argument DISPLAY_NAME with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-38093 since 04/06/2026. The exploitation is known to be easy. An attack has to be approached locally. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
