{"id":"EEF-CVE-2026-48592","summary":"Missing authorization check on save-job event handler in oban_web","details":"## Summary\n\nMissing 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.\n\n## Configuration\n\nThe Oban.Web dashboard must be deployed and accessible to users with less than full job-management privileges (e.g. :read_only).","aliases":["CVE-2026-48592","GHSA-389x-rgxr-8m33"],"modified":"2026-05-27T16:00:04.195592367Z","published":"2026-05-26T19:46:48.611Z","database_specific":{"cwe_ids":["CWE-862"],"cpe_ids":["cpe:2.3:a:oban_web_project:oban_web:*:*:*:*:*:*:*:*"],"capec_ids":["CAPEC-1"]},"references":[{"type":"ADVISORY","url":"https://github.com/oban-bg/oban_web/security/advisories/GHSA-389x-rgxr-8m33"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-48592.html"},{"type":"FIX","url":"https://github.com/oban-bg/oban_web/commit/ab3c5d1d3eba06c62045f16f2cd7781c7752e248"},{"type":"PACKAGE","url":"https://hex.pm/packages/oban_web"}],"affected":[{"package":{"name":"oban_web","ecosystem":"Hex","purl":"pkg:hex/oban_web"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.12.0"},{"fixed":"2.12.5"}]}],"versions":["2.12.0","2.12.1","2.12.2","2.12.3","2.12.4"],"database_specific":{"source":"https://cna.erlef.org/osv/EEF-CVE-2026-48592.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/oban-bg/oban_web.git","events":[{"introduced":"a17bc8c31286c9d516e2892cf5483d1c95e65d6c"},{"fixed":"ab3c5d1d3eba06c62045f16f2cd7781c7752e248"}]}],"versions":["v2.12.4","v2.12.3","v2.12.2","v2.12.1","v2.12.0"],"database_specific":{"source":"https://cna.erlef.org/osv/EEF-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"}],"credits":[{"name":"Peter Ullrich","type":"FINDER"},{"name":"Parker Selbert","type":"REMEDIATION_DEVELOPER"},{"name":"Jonatan Männchen / EEF","type":"ANALYST"}]}
