high

Description

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.
