CVE-2026-42611: Getgrav Grav

High severity, CVSS 8.9. EPSS: 0.4% chance of exploitation in the next 30 days.

Grav is a file-based Web platform. Prior to 2.0.0-beta.2, a low-privileged (with the ability to create a page) user can cause XSS with the injection of svg element. The XSS can further be escalated to dump the entire system information available under /admin/config/info whenever a Super Admin visits the page; which can further be chained with the use of admin-nonce to do a complete server compromise (RCE). This vulnerability is fixed in 2.0.0-beta.2.

Affected products

• Getgrav Grav: up to and including 1.8.0; version 2.0.0 only
