CyberRota Analysis
AI-GeneratedThe ash_oban library is vulnerable to an uncontrolled recursion issue that can be exploited by users triggering the on_error action, leading to excessive CPU and memory consumption. This results in a denial-of-service condition as the worker processes become overwhelmed and ultimately terminated. Organizations using affected versions (0.8.0-rc.1 to 0.8.14) should prioritize patching to mitigate potential service disruptions.

Original NVD Description
Uncontrolled Recursion vulnerability in ash-project ash_oban allows a user who can drive a trigger's on_error action to fail on the final attempt to exhaust worker CPU and memory, denying service. The generated worker's atomic handle_error/4 runs the trigger's on_error action on a job's final attempt inside a rescue that, when the action itself raises, calls handle_error/4 again with the same job. The job's attempt still equals max_attempts, so it re-enters the same clause and re-runs the failing action, with no exit. Any deterministic on_error failure (a data-layer outage, a misconfigured action, or a record the action rejects) loops forever; because the recursive call is not in tail position, each iteration retains a formatted stacktrace and the process heap grows without bound while the failing statement is re-issued against the data layer until the runtime kills the worker. This issue affects ash_oban: from 0.8.0-rc.1 before 0.8.14.
