Detailsinfo

A vulnerability classified as problematic has been found in ash-project ash_oban up to 0.8.13. Affected is the function handle_error. The manipulation with an unknown input leads to a recursion vulnerability. CWE is classifying the issue as CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-78228 since 08/30/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.
