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.","state":0,"publishedAt":"2026-10-21T18:17:24.957+00:00","modifiedAt":"2026-10-22T17:21:57.293+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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","score":8.6,"severity":"HIGH"}],"references":["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/pull/36726","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","https://github.com/storybookjs/storybook/security/advisories/GHSA-f2ph-cmg5-wxc8"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114125","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-94","CWE-346","CWE-1021"],"productCriteria":[],"sourceDates":{"published":"2026-10-21T18:17:24.957","lastModified":"2026-10-22T17:21:57.293"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
