{"id":"CVE-2026-48592","summary":"Missing authorization check on save-job event handler in oban_web","details":"Missing Authorization vulnerability in oban-bg oban_web ('Elixir.Oban.Web.Jobs.DetailComponent' modules) allows unauthorized job worker substitution.\n\nThe handle_event(\"save-job\", ...) handler in 'Elixir.Oban.Web.Jobs.DetailComponent' does not perform an authorization check, unlike the sibling cancel, delete, and retry handlers which all verify the caller's privileges via can?/2. An authenticated user with :read_only access can push a forged save-job LiveView WebSocket event to overwrite a job's worker field with any other existing Oban.Worker module in the application. On the job's next execution attempt, Oban will invoke perform/1 on the attacker-chosen module instead of the intended one.\n\nThis issue affects oban_web: from 2.12.0 before 2.12.5.","aliases":["EEF-CVE-2026-48592","GHSA-389x-rgxr-8m33"],"modified":"2026-06-18T03:57:43.260728829Z","published":"2026-05-26T19:46:48.611Z","database_specific":{"cna_assigner":"EEF","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"a17bc8c31286c9d516e2892cf5483d1c95e65d6c"},{"fixed":"ab3c5d1d3eba06c62045f16f2cd7781c7752e248"}]}],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48592.json","cwe_ids":["CWE-862"]},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-48592.html"},{"type":"WEB","url":"https://github.com"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-48592"},{"type":"WEB","url":"https://repo.hex.pm"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48592.json"},{"type":"ADVISORY","url":"https://github.com/oban-bg/oban_web/security/advisories/GHSA-389x-rgxr-8m33"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48592"},{"type":"FIX","url":"https://github.com/oban-bg/oban_web/commit/ab3c5d1d3eba06c62045f16f2cd7781c7752e248"},{"type":"PACKAGE","url":"https://github.com/oban-bg/oban_web.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/oban-bg/oban_web","events":[{"introduced":"f23d19f035a36430f898c35fcd2168784c427a59"},{"fixed":"a01100b9405fa62009bc1674d5b2bd2acc27e07e"},{"fixed":"ab3c5d1d3eba06c62045f16f2cd7781c7752e248"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"2.12.0"},{"fixed":"2.12.5"}]}}],"versions":["v2.12.4","v2.12.3","v2.12.2","v2.12.1","v2.12.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-48592.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
