CVE-2026-85598: Getgrav Grav

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

Grav versions 2.0.0 through 2.0.17 fail to apply save-time XSS detection to modular pages, allowing authenticated page editors to store Twig-assembled XSS payloads. Attackers with page-edit rights can create modular pages with malicious Twig code that executes in visitor browsers when the parent page is rendered, including in administrator sessions.

Affected products

• Getgrav Grav: from 2.0.0, up to and including 2.0.17
