{"id":"CVE-2026-114125","published":"2026-10-21T18:17:24.957","lastModified":"2026-10-22T17:21:57.293","description":"Storybook is a frontend workshop for building user interface components and pages in isolation. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-94","CWE-346","CWE-1021"],"vendors":[],"products":[],"references":[{"url":"https://github.com/storybookjs/storybook/commit/243c06bf8f1e2f09446c44868ea100261e1374da","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/3be03ec6f11f4616471cebc3fc65c13e1bf8c178","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/97513d999910d071c2b36830495dab63e17d9fe0","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/d9b09e332510a88689c71ecc081bbbc2d072476e","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/df3fed468c9b4830605f00068c4bc6b7e1e215ed","tags":[]},{"url":"https://github.com/storybookjs/storybook/pull/36726","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v10.6.2","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v11.0.0-alpha.6","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v8.6.19","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v9.1.21","tags":[]},{"url":"https://github.com/storybookjs/storybook/security/advisories/GHSA-f2ph-cmg5-wxc8","tags":[]}],"exploitRefs":[{"url":"https://github.com/storybookjs/storybook/commit/243c06bf8f1e2f09446c44868ea100261e1374da","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/3be03ec6f11f4616471cebc3fc65c13e1bf8c178","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/97513d999910d071c2b36830495dab63e17d9fe0","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/d9b09e332510a88689c71ecc081bbbc2d072476e","tags":[]},{"url":"https://github.com/storybookjs/storybook/commit/df3fed468c9b4830605f00068c4bc6b7e1e215ed","tags":[]},{"url":"https://github.com/storybookjs/storybook/pull/36726","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v10.6.2","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v11.0.0-alpha.6","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v8.6.19","tags":[]},{"url":"https://github.com/storybookjs/storybook/releases/tag/v9.1.21","tags":[]},{"url":"https://github.com/storybookjs/storybook/security/advisories/GHSA-f2ph-cmg5-wxc8","tags":[]}],"hasPoc":true,"ai":null}
