CVE-2025-47929Public exploitNetwork attack vector

Script execution via unsanitized uploaded filenames

Published May 15, 2025 · Updated May 28, 2025

DOM XSS in DumbDrop before commit db27b25372eb9071e63583d8faed2111a2b79f1b allows context-dependent attackers to run script via a crafted filename. Upload-list rendering inserts folder names, relative paths, and filenames into innerHTML, causing embedded markup to be interpreted instead of displayed as text. A user must select the crafted file, after which its script runs in the DumbDrop origin without requiring an account.
