CVE-2025-68429: 
JavaScript Schwachstellenanalyse und -minderung

Storybook is a frontend workshop for building user interface components and pages in isolation. A vulnerability present starting in versions 7.0.0 and prior to versions 7.6.21, 8.6.15, 9.1.17, and 10.1.10 relates to Storybook’s handling of environment variables defined in a .env file, which could, in specific circumstances, lead to those variables being unexpectedly bundled into the artifacts created by the storybook build command. When a built Storybook is published to the web, the bundle’s source is viewable, thus potentially exposing those variables to anyone with access. For a project to potentially be vulnerable to this issue, it must build the Storybook (i.e. run storybook build directly or indirectly) in a directory that contains a .env file (including variants like .env.local) and publish the built Storybook to the web. Storybooks built without a .env file at build time are not affected, including common CI-based builds where secrets are provided via platform environment variables rather than .env files. Storybook runtime environments (i.e. storybook dev) are not affected. Deployed applications that share a repo with your Storybook are not affected. Users should upgrade their Storybook—on both their local machines and CI environment—to version .6.21, 8.6.15, 9.1.17, or 10.1.10 as soon as possible. Maintainers additionally recommend that users audit for any sensitive secrets provided via .env files and rotate those keys. Some projects may have been relying on the undocumented behavior at the heart of this issue and will need to change how they reference environment variables after this update. If a project can no longer read necessary environmental variable values, either prefix the variables with STORYBOOK_ or use the env property in Storybook’s configuration to manually specify values. In either case, do not include sensitive secrets as they will be included in the built bundle.
