Name of the Vulnerable Software and Affected Versions Yuko Yuko (aka jp.co.yukoyuko.android.yukoyuko android) versions 1.0.5 and earlier

Description The issue allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate, as the application does not verify X.509 certificates from SSL servers.

Recommendations For versions 1.0.5 and earlier, consider implementing certificate pinning or verifying X.509 certificates from SSL servers to prevent man-in-the-middle attacks. As a temporary workaround, restrict the application's access to sensitive information until a proper fix is applied.
