Is this vulnerability remotely exploitable over the internet?

It can be, if the Tactical RMM interface or API is exposed to remote users who hold credentials. The vulnerability requires authenticated access to create a new agent but does not inherently require local network access.

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

The attacker must be an authenticated user with the ability to create agents through the `/api/v3/newagent/` endpoint. They do not need administrative privileges; the exploit targets admins who later view the compromised agent in the management UI.

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

The safest pattern is to treat all user-controlled fields as plain text and apply strict server-side validation plus context-appropriate output encoding before rendering. Only allow HTML input in carefully controlled components, and even then, restrict to a minimal, well-reviewed subset.
