The vulnerability arises from the lack of sanitization or HTML encoding of the `content` field when deserializing user-provided data. This allows an attacker to inject malicious HTML or JavaScript payloads, which can be executed in the context of another user\u0027s browser. Exploitation of this vulnerability can lead to account takeover, session hijacking, or wormable attacks."
