CVE-2022-47717Public exploitNetwork attack vector

Cross-origin response disclosure via permissive CORS header

Published Feb 1, 2023 · Updated Mar 27, 2025

CORS misconfiguration in Last Yard 22.09.8-1 allows remote attackers to read cross-origin web responses without authentication. The referenced HTTP trace shows an SVG response with Access-Control-Allow-Origin set to *., but provides no request context or browser evidence. The condition is network-reachable without authentication; however, public evidence identifies no sensitive endpoint beyond the demonstrated SVG asset.
