The Shein Group Ltd. "SHEIN - Fashion Shopping" app -- aka shein fashion-shopping/id878577184 -- for iOS does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
The product does not validate, or incorrectly validates, a certificate.
