{"id":"CVE-2026-83805","summary":"Nautobot: Authorization bypass in approval workflow REST API allows self-approval and unauthorized activation of scheduled jobs","details":"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.","aliases":["GHSA-q4c5-2j6f-r476","PYSEC-2026-4111"],"modified":"2026-10-01T17:56:10.652773917Z","published":"2026-09-22T19:47:42.826Z","database_specific":{"cwe_ids":["CWE-285","CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/83xxx/CVE-2026-83805.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/nautobot/nautobot/releases/tag/v3.1.8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/83xxx/CVE-2026-83805.json"},{"type":"ADVISORY","url":"https://github.com/nautobot/nautobot/security/advisories/GHSA-q4c5-2j6f-r476"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83805"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/commit/8682707d0391cbfd7694e3276127b78dc9cf29d8"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nautobot/nautobot","events":[{"introduced":"b9e675881bc7cc1ce7896637828972e691860c91"},{"fixed":"8682707d0391cbfd7694e3276127b78dc9cf29d8"},{"fixed":"106c8aaba19d92c83b55830f9b68a164e473ab5f"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.1.8"}]}}],"versions":["v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.11","v3.0.10","v3.0.9","v3.0.8","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-83805.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"}]}
