Description OSIDB Bzimport 2025-12-03 09:07:24 UTC
This vulnerability allows a malicious website to read arbitrary local files by abusing the file drag-and-drop mechanism in WebKitGTK. The flaw exists because WebKitGTK does not verify that drag operations originate from outside the browser before granting access to the referenced file path. A crafted webpage can prompt the user to perform an innocent-looking drag action that unintentionally exposes sensitive file content accessible to the user account. This results in a remote, user-assisted information disclosure vulnerability that can reveal any file the user is permitted to read.

JFTR, this is part of <https://webkitgtk.org/security/WSA-2025-0009.html> and it was fixed upstream in version 2.50.3.

It would be nice if upstream WSA can be added as a reference too.
