Summary
In oban_web (Elixir.Oban.Web.Jobs.DetailComponent), the handle_event("save-job", ...) handler lacks authorization, allowing an authenticated user with read-only access to overwrite a job's worker field with any other Oban.Worker module. Other handlers (cancel, delete, retry) check permissions, but save-job does not.
Risk Assessment
An authenticated attacker with low privileges can replace the job's worker module, potentially leading to unauthorized code execution or privilege escalation.
Recommendation
Update oban_web to version 2.12.5 or later, which includes the fix adding authorization checks.
Other vulnerabilities in oban_web
Original NVD description (English source)
Missing Authorization vulnerability in oban-bg oban_web ('Elixir.Oban.Web.Jobs.DetailComponent' modules) allows unauthorized job worker substitution. The handle_event("save-job", ...) handler in 'Elixir.Oban.Web.Jobs.DetailComponent' does not perform an authorization check, unlike the sibling cancel, delete, and retry handlers which all verify the caller'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's worker field with any other existing Oban.Worker module in the application. On the job's next execution attempt, Oban will invoke perform/1 on the attacker-chosen module instead of the intended one. This issue affects oban_web: from 2.12.0 before 2.12.5.
