How widely exploitable is this vulnerability?

Exploitability depends on who can influence the data feeding the tag creation logic and who visits the affected pages; if attackers can get privileged users to load crafted URLs or content, the vulnerability can have significant impact.

Does an attacker need authenticated access to exploit this issue?

Not necessarily. In many scenarios, the attacker only needs to convince an authenticated administrator or editor to interact with a crafted link or page where the untrusted data reaches the vulnerable DOM sink.

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

The most reliable pattern is to eliminate unsafe DOM writes by using text-only DOM APIs combined with consistent, context-aware output encoding for any data that might be influenced by users or external inputs.
