CVE-2025-66300Public exploitNetwork attack vector

Authenticated file disclosure via unrestricted Twig file reads

Published Dec 1, 2025 · Updated Dec 2, 2025

Path traversal in GetGrav Grav before 1.8.0-beta.27 allows remote authenticated users with page-editing rights to read server files. The Twig readFileFunc used by the Frontmatter display template passes the resolved path to file_get_contents without verifying that it remains under GRAV_ROOT. Page-editing access is sufficient to expose account YAML files containing password hashes, two-factor secrets, and password-reset tokens.
