Is this vulnerability remotely exploitable?

Yes. Any attacker who can obtain a Teacher-level account, or compromise one, can exploit the vulnerability over the network by crafting malicious glossary entries that will be executed in an administrator's browser.

What level of access is required to exploit this issue?

The attacker needs authenticated Teacher-level access or equivalent permissions that allow creating or editing glossary entries. Guest or student users without glossary edit rights cannot directly exploit this specific flaw.

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

The most robust approach is to apply context-aware output encoding by default and use a vetted sanitization library for any user-generated HTML. Templates should not render raw user input; instead, they should escape all variables unless there is a strong, reviewed justification not to.
