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."}],"title":"BackWPup <= 5.6.6 - Authenticated (Administrator+) Local File Inclusion via 'block_name' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/084e3f78-275b-4692-9cce-e17074f55cfb?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/tags/5.6.5/inc/Utils/BackWPupHelpers.php#L23"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/trunk/inc/Utils/BackWPupHelpers.php#L23"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/tags/5.6.5/inc/Utils/BackWPupHelpers.php#L40"},{"url":"https://plugins.trac.wordpress.org/browser/backwpup/tags/5.6.5/src/Frontend/API/Rest.php#L52"},{"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"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","cweId":"CWE-22","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"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"}}],"credits":[{"lang":"en","type":"finder","value":"JOAO PEDRO VENTURA ALVES"}],"timeline":[{"time":"2026-04-13T14:13:09.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-14T13:01:06.063780Z","id":"CVE-2026-6227","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-14T13:03:30.768Z"}}]}}
