From 8.0.0 until 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6, a malicious website can interact with the preview of a running Storybook development server. Insufficient iframe embedding and message-origin restrictions can allow attacker-controlled events to reach the running preview. A developer must visit the malicious website and interact with the injected interface. The attack can cause unauthorized changes to story files and, if a changed file is later executed by a local runtime, arbitrary code execution with the developer's privileges. This issue is fixed in 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6.","score":8.6,"severity":"high","published":"2026-10-21T17:08:12.102Z","modified":"2026-10-28T17:13:06.610Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"storybookjs","name":"storybook","platforms":[],"versions":[{"version":">= 8.0.0, < 8.6.19","status":"affected"},{"version":">= 9.0.0, < 9.1.21","status":"affected"},{"version":">= 10.0.0, < 10.6.2","status":"affected"},{"version":">= 11.0.0-alpha.0, < 11.0.0-alpha.6","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-114125"}],"remediation":[],"references":["https://github.com/storybookjs/storybook/security/advisories/GHSA-f2ph-cmg5-wxc8","https://github.com/storybookjs/storybook/pull/36726","https://github.com/storybookjs/storybook/commit/243c06bf8f1e2f09446c44868ea100261e1374da","https://github.com/storybookjs/storybook/commit/3be03ec6f11f4616471cebc3fc65c13e1bf8c178","https://github.com/storybookjs/storybook/commit/97513d999910d071c2b36830495dab63e17d9fe0","https://github.com/storybookjs/storybook/commit/d9b09e332510a88689c71ecc081bbbc2d072476e","https://github.com/storybookjs/storybook/commit/df3fed468c9b4830605f00068c4bc6b7e1e215ed","https://github.com/storybookjs/storybook/releases/tag/v10.6.2","https://github.com/storybookjs/storybook/releases/tag/v11.0.0-alpha.6","https://github.com/storybookjs/storybook/releases/tag/v8.6.19","https://github.com/storybookjs/storybook/releases/tag/v9.1.21"],"sources":[{"name":"CVE","id":"CVE-2026-114125","modified":"2026-10-28T17:13:06.610Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-114125"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.6}],"sourceAffected":[],"observedAt":"2026-10-29T14:33:36.295Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T00:50:33.640Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-28T17:50:32.374Z","attemptedAt":"2026-10-28T17:50:32.374Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-28T17:50:32.036Z","attemptedAt":"2026-10-28T17:50:32.036Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-28T17:50:31.884Z","attemptedAt":"2026-10-28T17:50:31.884Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-28T17:50:32.278Z","attemptedAt":"2026-10-28T17:50:32.278Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-107393","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-107393","modified":"Oct 21, 2026, 5:08:12 PM","score":8.6,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","checkedAt":"2026-10-28T17:50:31.884Z"},{"source":"GitHub Advisory Database","id":"GHSA-f2ph-cmg5-wxc8","url":"https://github.com/advisories/GHSA-f2ph-cmg5-wxc8","modified":"2026-10-21T17:23:30Z","checkedAt":"2026-10-28T17:50:32.036Z"},{"source":"FIRST EPSS","id":"CVE-2026-114125","url":"https://www.first.org/epss/","probability":0.00385,"percentile":0.32438,"date":"2026-10-28","checkedAt":"2026-10-28T17:50:32.278Z"},{"source":"NVD","id":"CVE-2026-114125","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114125","modified":"2026-10-22T17:21:57.293","score":8.6,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","checkedAt":"2026-10-28T17:50:32.374Z"}],"aiSummary":{"text":"Storybook versions 8.0.0 to 8.6.19, 9.0.0 to 9.1.21, 10.0.0 to 10.6.2, and 11.0.0-alpha.0 to 11.0.0-alpha.6 have a code injection weakness due to missing origin validation, allowing a malicious website to interact with the preview of a running Storybook development server if a developer visits the site.
