Is this vulnerability remotely exploitable over the web?

Yes. Any attacker who can obtain a valid student account and access the web interface can store malicious content in profile fields. Other users who view the affected profiles through their browsers can then be impacted without additional user interaction beyond normal navigation.

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

The attacker needs authenticated access with permissions to edit profile information—typically a standard student-level account. Elevated privileges (such as instructor or administrator) are not required to plant the payload, but higher-privileged users may be the most valuable targets when they view compromised profiles.

What is the safest general fix pattern for this type of bug?

The most robust pattern is to enforce strict, context-aware output encoding for all user-supplied data at every rendering point, combined with server-side sanitization for fields that intentionally allow limited markup. This should be implemented using centralized template helpers or frameworks that escape output by default, rather than relying on ad hoc manual escaping.
