This makes it possible for unauthenticated attackers to include remote files on the server, resulting in code execution. NOTE: Successful exploitation of this vulnerability requires that the target server's php.ini is configured with 'allow_url_include' set to 'on'. This feature is deprecated as of PHP 7.4 and is disabled by default, but can still be explicitly enabled in later versions of PHP.","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-829"],"references":["https://plugins.trac.wordpress.org/browser/backup-backup/tags/1.3.9/includes/backup-heart.php","https://plugins.trac.wordpress.org/changeset/3012745/backup-backup","https://www.wordfence.com/threat-intel/vulnerabilities/id/b380283c-0dbb-4d67-9f66-cb7c400c0427?source=cve","https://plugins.trac.wordpress.org/browser/backup-backup/tags/1.3.9/includes/backup-heart.php","https://plugins.trac.wordpress.org/changeset/3012745/backup-backup"],"products":["backupbliss:backup_migration"],"source":"nvd","synced_at":"2026-10-19T21:43:38.875533635+00:00"},"epss":{"cve":"CVE-2023-6971","score":0.06419,"percentile":0.93698,"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).
