{"schemaVersion":3,"id":"CVE-2026-84718","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A flaw was found in the Ansible Automation Platform automation-controller. In the shipped\nproduction configuration, the Controller trusts the client-supplied X-Forwarded-For header as\nthe request's client IP without verifying that it originated from a trusted proxy, and selects\nthe leftmost (attacker-controlled) header value. As a result, an attacker can forge the source\nIP address recorded for their requests in the Controller's audit and access logs, degrading\nthe integrity of forensic and SIEM attribution. The flaw does not grant additional access.","dates":{"published":"2026-09-23T19:40:33.062Z","modified":"2026-10-16T11:55:19.754Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":4.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00136,"percentile":0.0271,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-09-24T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00136,"percentile":0.0271}],"last30":[{"date":"2026-09-24T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00136,"percentile":0.0271}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":n
