CVE-2026-72820Public exploitNetwork attack vector

Sensitive-file disclosure via unchecked backup root

Published Aug 14, 2026 · Updated Aug 14, 2026

Path traversal in GetGrav Grav 2.0.11 through 2.0.12 allows remote authenticated users to archive files outside GRAV_ROOT. Backups::backup resolves a profile-controlled root with realpath() but accepts an out-of-root directory whenever it is absent from a hard-coded deny-list. Profile-editor access is required; a configured profile can place sensitive files from nonblocked server directories into a backup archive.
