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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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,"severity":null}],"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"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-107393","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 21, 2026, 5:08:12 PM","dateUpdated":"Oct 28, 2026, 5:13:06 PM"},"relatedAdvisories":[{"id":"RHSA-2026:88541","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update","vulnerabilityIds":["CVE-2026-40895","CVE-2026-111755","CVE-2026-111756","CVE-2026-114125","CVE-2026-114126"]},{"id":"RHSA-2026:88537","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update","vulnerabilityIds":["CVE-2026-111755","CVE-2026-111756","CVE-2026-114125","CVE-2026-114126"]},{"id":"RHSA-2026:88478","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update","vulnerabilityIds":["CVE-2026-111755","CVE-2026-111756","CVE-2026-114125","CVE-2026-114126"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
