{"id":"CVE-2026-78228","summary":"Unbounded handle_error recursion enables denial of service in AshOban triggers","details":"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.\n\nThe 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.\n\nThis issue affects ash_oban: from 0.8.0-rc.1 before 0.8.14.","aliases":["EEF-CVE-2026-78228","GHSA-94p7-498r-mrhp"],"modified":"2026-09-03T03:30:52.501229917Z","published":"2026-08-30T11:51:49.621Z","database_specific":{"cna_assigner":"EEF","cwe_ids":["CWE-674"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/78xxx/CVE-2026-78228.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"5d117ed2006df7277561c69dbfd39281da6ace9f"},{"fixed":"851cd0e76ed882bf736fc48d10f96d037e26b5f0"}]}]},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-78228.html"},{"type":"WEB","url":"https://github.com"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-78228"},{"type":"WEB","url":"https://repo.hex.pm"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/78xxx/CVE-2026-78228.json"},{"type":"ADVISORY","url":"https://github.com/ash-project/ash_oban/security/advisories/GHSA-94p7-498r-mrhp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78228"},{"type":"FIX","url":"https://github.com/ash-project/ash_oban/commit/851cd0e76ed882bf736fc48d10f96d037e26b5f0"},{"type":"PACKAGE","url":"https://github.com/ash-project/ash_oban"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ash-project/ash_oban","events":[{"introduced":"075a42a2671073c8270401c9478d5af4dfe72bf6"},{"fixed":"d918a299d73ac9f0d85e55b8533ddb4801a3af2d"},{"fixed":"851cd0e76ed882bf736fc48d10f96d037e26b5f0"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0.8.0-rc.1"},{"fixed":"0.8.14"}]}}],"versions":["v0.8.13","v0.8.12","v0.8.11","v0.8.10","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0-rc.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-78228.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","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"}]}
