EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 82% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Grav is a file-based Web platform. Prior to 1.7.53, an authenticated administrator with backup permissions can download a ZIP archive containing the full Grav installation root, including user/accounts/admin.yaml with the administrator password hash and user/config with site configuration, through the backup download endpoint protected only by the session-static admin-nonce URL parameter. This issue is reported as fixed in version 1.7.53.
