Path Traversal in Grav CMS Backup Profiles

Publication date: 2026-08-14

Last updated on: 2026-08-14

Assigner: VulnCheck

Description
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.

Executive Summary

CVE-2026-72820 is a path traversal vulnerability in Grav CMS versions before 2.0.13. It allows attackers with profile editor access to configure backup profiles with traversal paths, enabling them to archive directories outside the Grav installation root (GRAV_ROOT). This can expose sensitive files from locations like /opt, /mnt, or /srv.

Detection Guidance

Check Grav CMS version with 'bin/grav version' or inspect the composer.json file for version constraints. Look for unauthorized backup profiles in the Grav admin panel or filesystem under user/config/backups.yaml. Review system logs for suspicious backup operations targeting directories like /opt, /mnt, or /srv.

Impact Analysis

An attacker could exploit this to access sensitive files outside Grav's installation directory, potentially exposing application data, secrets, or other confidential information. This could lead to data breaches, unauthorized access, or further system compromise if critical system files are exposed.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage due to data exposure.

Mitigation Strategies

Upgrade Grav CMS to version 2.0.13 or later immediately. Remove or restrict access for any backup profiles that include traversal paths. Audit all backup configurations and disable the profile editor role for non-trusted users until patched.
