CVE-2026-75829 PUBLISHED

grav-plugin-api before 1.0.15 Twig SSTI via translate endpoint

Assigner: VulnCheck
Reserved: 18.08.2026 Published: 18.08.2026 Updated: 18.08.2026

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.
