Stored XSS via unsanitized folder path
Published Feb 1, 2026 · Updated Feb 1, 2026
Stored XSS in QWE DL 2.0.1 allows remote attackers to run scripts through crafted folder paths in its GCDWebUploader interface. The create-folder POST handler stores the path value without neutralizing script markup, which later executes when the index or a subfolder view renders that path. Exploitation requires network access to the app's Wi-Fi transfer interface and low user interaction; execution can hijack a session or alter application content.
