This makes it possible for authenticated attackers, with Administrator-level access and above, to include arbitrary PHP files on the server via crafted traversal sequences (e.g., `....//`), which can be leveraged to read sensitive files such as `wp-config.php` or achieve remote code execution in certain configurations. Administrators have the ability to grant individual users permission to handle backups, which may then allow lower-level users to exploit this vulnerability."}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":7.2,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.2,"impactScore":5.9}]},"weaknesses":[{"source":"security@wordfence.com","type":"Primary","description":[{"lang":"en","value":"CWE-22"}]}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/backwpup/tags/5.6.5/inc/Utils/BackWPupHelpers.php#L23","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/tags/5.6.5/inc/Utils/BackWPupHelpers.php#L40","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/tags/5.6.5/src/Frontend/API/Rest.php#L52","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/trunk/inc/Utils/BackWPupHelpers.php#L23","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3490642%40backwpup%2Ftrunk&old=3475739%40backwpup%2Ftrunk&sfp_email=&sfph_mail=#file26","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/084e3f78-275b-4692-9cce-e17074f55cfb?source=cve","source":"security@wordfence.com"}]}}]}
