CVE-2026-112781 · Severity: medium · CVSS 6.5 · Published 2026-10-19

Grav is a flat-file CMS that allows content editing through a web interface. An attacker with page-edit permissions can inject special directives into page forms to bypass security restrictions and read sensitive configuration values—such as encryption keys, plugin credentials, and database passwords—which are then exposed to all site visitors.

## Technical details

The vulnerability exists in Blueprint dynamic directives, where config-*@ directives are not validated for provenance like data-*@ directives are. This allows page-authored forms to call Config::get() without filtering, bypassing the Twig sandbox's config_denied_paths redaction. An authenticated attacker with api.pages.write or admin.pages permission can inject these directives into frontmatter forms to disclose restricted configuration paths (security.salt, plugin credentials, Redis passwords) to unauthorized users.

## Affected products

- Getgrav Grav 2.0.0 through 2.2.1
