Vulnerability Title
Grav: Twig sandbox allows editor-role users to exfiltrate all plugin secrets via Config::toArray()
Source: CVE Program / CVE List V5
Vulnerability Description
Grav is a file-based Web platform. Prior to 2.0.0-rc.2, the Twig sandbox allow-list permits any user with the admin.pages role to call config.toArray() from within a page body, dumping the entire merged site configuration — including all plugin secrets (SMTP passwords, AWS keys, OAuth client secrets, API tokens) — into the rendered HTML. No administrator privileges are required. This vulnerability is fixed in 2.0.0-rc.2.
