Summary
Grav from 2.0.0 before 2.2.2 contains an information disclosure flaw (CWE-200) in its form handling. Page editors can add config-*@ directives to page frontmatter forms, which bypasses the Twig sandbox config_denied_paths redaction. An attacker with page-edit permission can expose security.salt, plugin credentials, and Redis passwords to all visitors, with no privileges needed beyond page editing.
