From 8.0.0 until 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6, the Storybook development server can expose its WebSocket authentication token to clients able to load its HTML pages over a local network. A LAN attacker can obtain the token and invoke WebSocket-backed file-writing or testing functionality. Weak story-write validation can allow code to be placed in story files. If the Storybook Vitest addon is installed with an old version of Vitest, the payload can use a Vitest API to write additional files or execute commands. Depending on the payload and local tooling, the attack can lead to 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:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:N","score":8.7,"severity":null}],"references":["https://github.com/storybookjs/storybook/security/advisories/GHSA-px85-f4q5-jh77","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/5540f03b209cc56c66f56a9c7cb4b2ee5b883ce5","https://github.com/storybookjs/storybook/commit/a9ef9345d73224c73e0b81dc2701ec5b465ea9bb","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-2026-107408","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 21, 2026, 5:21:29 PM","dateUpdated":"Oct 28, 2026, 1:28:25 AM"},"relatedAdvisories":[{"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"]},{"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-2026:88541","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"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
