CVE-2026-92917Public exploitNetwork attack vectorHinoki check available

Configuration disclosure via sandboxed print_r filter

Published Sep 17, 2026 · Updated Sep 19, 2026

Information disclosure in Grav 2.0.0-rc.1 through 2.0.21 allows remote authenticated users to read the merged configuration. GravExtension::assertSandboxDumpSafe() queries only Twig's unused global sandbox flag, so print_r reflects the private Config object behind SandboxConfig instead of enforcing path redaction. Page-edit rights and Twig processing are required, and successful exploitation exposes plugin credentials, API tokens, webhook secrets, and cache passwords.
