How broadly exploitable is this vulnerability?

This vulnerability is broadly exploitable wherever users can supply or influence the Observations field which is later rendered in the History view. Any user capable of saving such data can potentially attack administrators or other privileged users who view the affected history entries.

Does an attacker need administrative access to exploit this issue?

No. The attacker typically only needs the ability to create or modify records that populate the Observations field. The attack becomes impactful when a higher-privileged user, such as an administrator, subsequently views the History page containing the stored payload.

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

The safest pattern is to enforce context-aware output encoding on all user-controlled data at render time, ideally using framework-level escaping that is enabled by default. When rich HTML is unavoidable, pair encoding with a conservative, well-maintained HTML sanitizer to strip scripts and unsafe attributes.
