CVE-2026-48592 Details
Description
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.
A missing authorization vulnerability has been identified in the Oban Web component of the Oban Background job processing library, specifically in versions 2.12.0 prior to 2.12.5. The issue arises in the 'Elixir.Oban.Web.Jobs.DetailComponent' module, where the 'handle_event("save-job", ...)' function lacks proper authorization checks. This omission allows authenticated users with read-only access to send forged WebSocket events that overwrite a job's worker field with any existing Oban.Worker module. As a result, during the next execution of the job, Oban will execute the 'perform/1' function on the substituted worker module instead of the original one.
Users can update to Oban Web version 2.12.5 or later, where this vulnerability has been patched.
