CVE-2025-23027Network attack vector

Credential disclosure via committed environment-example token

Published Jan 13, 2025 · Updated Jan 13, 2025

Cleartext credential exposure in Vercel next-forge before 3.0.11 allows remote attackers to obtain a BaseHub access token. The apps/web/.env.example template stores a populated BASEHUB_TOKEN value instead of an empty placeholder, so repository and generated-project copies disclose the credential. Exposure requires access to an affected template or a project derived from it, and the token grants only the BaseHub access authorized to that credential.
