Description

This security bulletin contains information about 1 vulnerability.


1) File And Directory Information Exposure (CVE-ID: CVE-2025-68429)

CWE-ID: CWE-538 - File And Directory Information Exposure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to insertion of sensitive information into externally-accessible build artifacts in the Storybook build output when building a Storybook in a directory containing a .env file and publishing the built Storybook to the web. A remote attacker can view the published bundle source to disclose sensitive information.

Only built and published Storybooks are affected; development runtime environments and deployed applications that share a repository with Storybook are not affected.
