CVE-2023-2138Network attack vector

GitHub token exposure via public runtime configuration

Published Apr 18, 2023 · Updated Feb 5, 2025

Credential exposure in NuxtLabs @nuxtlabs/github-module before 1.6.2 allows remote attackers to obtain a configured GitHub token. The module copies options.token or GITHUB_TOKEN into nuxt.options.runtimeConfig.public.github, making the credential available to client code. A Nuxt application must configure the module with a token; exposure grants the token's assigned GitHub repository permissions.
