CVE-2026-75829: Getgrav Grav

High severity, CVSS 8.1. EPSS: 0.4% chance of exploitation in the next 30 days.

grav-plugin-api versions before 1.0.15 fail to validate Twig content in the translate() endpoint, allowing attackers with api.pages.write permission to persist pages with process.twig enabled. Attackers can submit crafted header and content parameters to execute server-side template injection payloads that are evaluated at render time.

Affected products

• Getgrav Grav: before 1.0.15 (fixed in 1.0.15)
