{"cve":"CVE-2026-83805","nvd":{"published":"2026-09-22T20:17:09.487","modified":"2026-09-26T01:17:02.700","status":"Awaiting Analysis","description":"Nautobot is a Network Source of Truth and Network Automation Platform. From 3.0.0 until 3.1.8, the generic ApprovalWorkflowStageResponse create endpoint does not enforce approver-group membership, change permission on the object under review, or the one-response-per-user restriction applied by the intended approve and deny actions. A user with only extras.add_approvalworkflowstageresponse can submit approved responses directly, while writable user and state fields permit responses to be attributed to arbitrary users. These forged responses can satisfy min_approvers, approve the workflow, and activate its gated ScheduledJob without a legitimate approver. This issue is fixed in version 3.1.8.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-285","CWE-639"],"references":["https://github.com/nautobot/nautobot/commit/8682707d0391cbfd7694e3276127b78dc9cf29d8","https://github.com/nautobot/nautobot/releases/tag/v3.1.8","https://github.com/nautobot/nautobot/security/advisories/GHSA-q4c5-2j6f-r476"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-83805","score":0.00294,"percentile":0.22073,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-q4c5-2j6f-r476","url":"https://osv.dev/vulnerability/GHSA-q4c5-2j6f-r476","summary":"Nautobot: Authorization bypass in approval workflow REST API allows self-approval and unauthorized activation of scheduled jobs","modified":"2026-10-01T17:56:10.652773917Z","packages":[{"ecosystem":"PyPI","name":"nautobot","purl":"pkg:pypi/nautobot","ranges":[">=3.0.0 <3.1.8"],"fixed":["3.1.8"]}]},{"id":"PYSEC-2026-4111","url":"https://osv.dev/vulnerability/PYSEC-2026-4111","summary":"Nautobot: Authorization bypass in approval workflow REST API allows self-approval and unauthorized activation of scheduled jobs","modified":"2026-10-01T17:45:10.084187323Z","packages":[{"ecosystem":"PyPI","name":"nautobot","purl":"pkg:pypi/nautobot","ranges":[">=3.0.0 <3.1.8"],"fixed":["3.1.8"]}]}],"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).
