CVE-2025-13947: Webkit: webkitgtk: remote user-assisted information disclosure via file drag-and-drop

HighCVSS 7.4 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 29/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.35% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: The WebKitGTK Team webkitgtk 2.50.3.

Low priority for now. Upgrade to The WebKitGTK Team webkitgtk 2.50.3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
