CVE-2022-47715Public exploitNetwork attack vector

Cookie disclosure via missing Secure attribute

Published Feb 1, 2023 · Updated Mar 27, 2025

Cleartext cookie exposure in Last Yard 22.09.8-1 allows man-in-the-middle attackers to steal a cookie from HTTP traffic. The HTTP response sets the LastYardVersion cookie without the Secure attribute, permitting browsers to send it over an unencrypted connection. Network-path access is required, and the published evidence identifies cookie disclosure without establishing account takeover or any ability to modify data.
