Description
Missing Authorization vulnerability in oban-bg oban_web (&#39;Elixir.Oban.Web.Jobs.DetailComponent&#39; modules) allows unauthorized job worker substitution.<br />
<br />
The handle_event("save-job", ...) handler in &#39;Elixir.Oban.Web.Jobs.DetailComponent&#39; does not perform an authorization check, unlike the sibling cancel, delete, and retry handlers which all verify the caller&#39;s privileges via can?/2. An authenticated user with :read_only access can push a forged save-job LiveView WebSocket event to overwrite a job&#39;s worker field with any other existing Oban.Worker module in the application. On the job&#39;s next execution attempt, Oban will invoke perform/1 on the attacker-chosen module instead of the intended one.<br />
<br />
This issue affects oban_web: from 2.12.0 before 2.12.5.
