CVE-2025-59416Network attack vector

Unauthorized article publication via forked admin list

Published Sep 17, 2025 · Updated Sep 17, 2025

Missing authorization in The Scratch Channel tsc-web-client before 1.2 allows remote authenticated users to publish unauthorized articles. In src/pages/createArticles.jsx, a fork operator can change the client-side administrator list and submit an article-creation POST request without an independent authorization check. A low-privileged account and a fork with a modified administrator list are required; exploitation creates articles under unauthorized administrative authority.
