CVE-2024-1098Public exploitNetwork attack vector

Information disclosure via unchecked proxy URL

Published Jan 31, 2024 · Updated May 29, 2025

Information disclosure in REBUILD 3.5.0 through 3.5.5 allows remote attackers to read server-retrieved content via proxy-download. QiniuCloud.getStorageFile accepts the url parameter at /filex/proxy-download and returns content from the selected location without constraining the destination. No authentication or user interaction is required; the disclosed consequence is read-only exposure of content reachable from the server.
