Detailsinfo

A vulnerability has been found in Gradio (affected version not known) and classified as critical. This vulnerability affects some unknown functionality.

The CWE definition for the vulnerability is CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The 'deploy-website.yml' workflow in the gradio-app/gradio repository, specifically in the 'main' branch, is vulnerable to secrets exfiltration due to improper authorization. The vulnerability arises from the workflow's explicit checkout and execution of code from a fork, which is unsafe as it allows the running of untrusted code in an environment with access to push to the base repository and access secrets. This flaw could lead to the exfiltration of sensitive secrets such as GITHUB_TOKEN, HF_TOKEN, VERCEL_ORG_ID, VERCEL_PROJECT_ID, COMMENT_TOKEN, AWSACCESSKEYID, AWSSECRETKEY, and VERCEL_TOKEN. The vulnerability is present in the workflow file located at https://github.com/gradio-app/gradio/blob/72f4ca88ab569aae47941b3fb0609e57f2e13a27/.github/workflows/deploy-website.yml.
