Description
Grav from 2.0.22 before 2.1.7 contains an information disclosure vulnerability that allows page editors to read the Clockwork debugger token because the sandbox redaction list omits system.debugger.token. Attackers can render the token through editor-authored Twig and supply it as X-Clockwork-Auth to read profiler records with configuration, request metadata, and database queries.
