This is due to an attacker being able to control the values passed to an include, and subsequently leverage that to achieve remote code execution. This makes it possible for unauthenticated attackers to easily execute code on the server.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-94"],"references":["https://plugins.trac.wordpress.org/browser/backup-backup/tags/1.3.7/includes/backup-heart.php#L118","https://plugins.trac.wordpress.org/browser/backup-backup/tags/1.3.7/includes/backup-heart.php#L38","https://plugins.trac.wordpress.org/browser/backup-backup/tags/1.3.7/includes/backup-heart.php#L62","https://plugins.trac.wordpress.org/browser/backup-backup/tags/1.3.7/includes/backup-heart.php#L64","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3006541%40backup-backup&new=3006541%40backup-backup&sfp_email=&sfph_mail="],"products":["backupbliss:backup_migration"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-6553","score":0.97846,"percentile":0.99908,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
