Is this vulnerability remotely exploitable?

Yes, if an attacker can access the `send/raw` API remotely and craft malicious payloads, the vulnerability can be exploited once an admin user views the affected content in the web interface.

What level of access does an attacker need to exploit this issue?

The attacker typically needs valid API access or control over a system that uses the `send/raw` endpoint. Exploitation then relies on an administrator opening the corresponding page in the admin UI where the injected content is rendered.

What is the safest general fix pattern for this vulnerability class?

Enforce context-aware output encoding for all untrusted data before rendering it in views, and use robust HTML sanitization for any content that must support limited markup, ensuring that script execution and dangerous attributes are stripped.
