CVE-2022-26533Public exploitNetwork attack vector

Browser script execution via unsanitized plist data

Published Mar 12, 2022 · Updated Aug 3, 2024

Reflected XSS in Alist 2.0.10 through 2.1.0 allows remote attackers to execute script in a user's browser via a crafted plist URL. The Plist handler base64-decodes the route data and inserts the resulting URL and derived name into XML with fmt.Sprintf without output encoding. Exploitation requires a user to open the crafted endpoint; injected script runs in the Alist origin and can read or alter browser-accessible data.
