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":"2026-10-21T17:08:12.102+00:00","modifiedAt":"2026-10-21T17:08:12.102+00:00","affected":[{"ecosystem":"Vendor product","name":"storybook","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"storybookjs\",\n                    \"product\": \"storybook\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 8.0.0, < 8.6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 9.0.0, < 9.1.21\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 10.0.0, < 10.6.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 11.0.0-alpha.0, < 11.0.0-alpha.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"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":"HIGH"}],"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://www.cve.org/CVERecord?id=CVE-2026-114125","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114125","identifiers":["CVE-2026-114125"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
