Cross-Domain Attack

Definitions

1. An attack that abuses trust boundaries between different domains or origins, often by exploiting assumptions in browser security, authentication, or shared resources. Such attacks matter because cross-domain relationships frequently carry implicit trust that is only partially enforced.

   In plain English: An attack that exploits trust or interaction between different domains or origins.

   Example: "The browser extension created a cross-domain attack path that allowed one origin to influence another's privileged requests."
