CVE-2025-13947

A flaw was found in WebKitGTK. This vulnerability allows remote, user-assisted information disclosure that can reveal any file the user is permitted to read via abusing the file drag-and-drop mechanism where WebKitGTK does not verify that drag operations originate from outside the browser.

The Red Hat Product Security team has assessed the severity of this vulnerability as High, as it enables remote websites to extract arbitrary files from a user’s system with minimal interaction. Although some user action is required, the action can be trivial and easily induced by a malicious page. The issue arises from missing validation that a dragged file originated from an external application, enabling unintended file system access. Successful exploitation can compromise confidentiality of local user data.
