Vulnerability in oban_web (CVE-2026-48592)
Summary
Vulnerability in oban_web (CVE-2026-48592). Risk of unauthorized operations or information disclosure. Exploitable via oban_web. Mitigation: upgrade to 2.12.5 or later.
Original description
The description as published by the source.
Summary
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.
Configurations
The Oban.Web dashboard must be deployed and accessible to users with less than full job-management privileges (e.g. :read_only).
