CVE-2022-43140Public exploitNetwork attack vector

Unauthenticated arbitrary requests via unfiltered getCorsFile URL

Published Nov 17, 2022 · Updated Apr 30, 2025

SSRF in kkFileView 4.1.0 allows remote attackers to force the server to issue arbitrary requests through the url parameter. The getCorsFile method in OnlinePreviewController accepts attacker-controlled urlPath data and performs request access without filtering special characters. No authentication or user interaction is required; the server can contact attacker-chosen destinations, while response-data exposure is not established.
