CVE-2025-13947
Description
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.
Statement
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.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
