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.\n\nThis issue affects ash\\_oban: from 0.8.0-rc.1 before 0.8.14.\n\n## Configuration\n\nA trigger must declare an on\\_error action and run through the atomic worker branch. An attacker needs only to drive that on\\_error action into a deterministic failure (for example by pushing the record into a state the action rejects) and let the job reach its final attempt.","id":"EEF-CVE-2026-78228","modified":"2026-08-30T11:51:50.489308Z","published":"2026-08-30T11:51:49.621Z","references":[{"type":"ADVISORY","url":"https://github.com/ash-project/ash_oban/security/advisories/GHSA-94p7-498r-mrhp"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-78228.html"},{"type":"FIX","url":"https://github.com/ash-project/ash_oban/commit/851cd0e76ed882bf736fc48d10f96d037e26b5f0"},{"type":"PACKAGE","url":"https://hex.pm/packages/ash_oban"}],"related":[],"schema_version":"1.7.3","severity":[{"score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","type":"CVSS_V4"}],"summary":"Unbounded handle_error recursion enables denial of service in AshOban triggers","upstream":[]}
