FKIE_CVE-2026-72820

Vulnerability from fkie_nvd - Published: 2026-08-14 12:16 - Updated: 2026-09-08 20:32
Severity
4.9 (Medium) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
Summary
Grav versions before 2.0.13 fail to properly validate backup profile root paths, allowing attackers to archive directories outside GRAV_ROOT when not in the hard-coded deny-list. Attackers with profile editor access can configure backup profiles with traversal paths to expose sensitive files from locations like /opt, /mnt, or /srv.
