CVE-2020-10118Network attack vector

Demo-account file modification via Branding API

Published Mar 17, 2020 · Updated Aug 4, 2024

Improper authorization in the cPanel Branding API before 84.0.20 allows remote authenticated users to modify files through API calls. The public record identifies Branding API requests as the locus but does not disclose the affected endpoint or the missing demo-mode enforcement. Access to a demo account is the required gate, and successful requests permit file modification without a reported availability impact.
