Because Oban job arguments round-trip through JSON, the caller's keys arrive as strings, so Map.merge sees no collision and both keys survive. When the job is persisted the JSON object is de-duplicated keeping the last (string) key, and the worker reads the caller's value. The documentation describes :args as unable to affect the action, so an application that forwards user input into it for uniqueness scoping is exposed to authorization bypass and tenant isolation breaks.\n\nThis issue affects ash_oban: from 0.2.5 before 0.8.14.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","score":5.9},"cvss_v3":null,"cwes":["CWE-915"],"references":["https://cna.erlef.org/cves/CVE-2026-78038.html","https://github.com/ash-project/ash_oban/commit/da2d81e1e8e1dcc3e6ec8587cdb4f273575ffca3","https://github.com/ash-project/ash_oban/security/advisories/GHSA-gj9p-x393-rf9h","https://osv.dev/vulnerability/EEF-CVE-2026-78038","https://github.com/ash-project/ash_oban/security/advisories/GHSA-gj9p-x393-rf9h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-78038","score":0.00377,"percentile":0.31732,"date":"2026-10-31"},"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).
