{"cve":"CVE-2026-78228","nvd":{"published":"2026-08-30T12:17:18.380","modified":"2026-09-01T21:15:00.147","status":"Deferred","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.\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.","cvss_v4":{"vector":"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","score":5.9},"cvss_v3":null,"cwes":["CWE-674"],"references":["https://cna.erlef.org/cves/CVE-2026-78228.html","https://github.com/ash-project/ash_oban/commit/851cd0e76ed882bf736fc48d10f96d037e26b5f0","https://github.com/ash-project/ash_oban/security/advisories/GHSA-94p7-498r-mrhp","https://osv.dev/vulnerability/EEF-CVE-2026-78228","https://github.com/ash-project/ash_oban/security/advisories/GHSA-94p7-498r-mrhp"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-78228","score":0.0018,"percentile":0.07564,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
