The vulnerability can be exploited remotely over the network by unauthenticated attackers (PR:N) with low attack complexity (AC:L), requiring user interaction such as clicking a malicious link (UI:R). Successful exploitation enables script execution in the context of the targeted user's browser, with a changed scope (S:C) that allows limited impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), such as session hijacking, data theft, or page manipulation for authenticated users like site administrators.
