Is this vulnerability remotely exploitable?

Yes. Any attacker who can register or obtain an ordinary user account on the affected Discourse instance and create or edit posts where the plugin is active could potentially exploit the issue remotely via the web interface.

What level of access does an attacker need?

The attacker needs authenticated access with normal posting privileges in at least one area where the policy plugin is enabled. Administrative or staff privileges are not required if the vulnerability is present.

What is the safest general fix pattern?

The safest fix is to enforce strict, centralized authorization checks on all policy widget creation and modification paths, ensuring only users in explicitly allowed groups (such as admins or designated staff groups) can create functional policy prompts. Separating policy management from general post content and applying least privilege to all plugin operations further reduces risk.
