This is due to insufficient validation of the `kbd_path` parameter, which is only sanitized with `sanitize_text_field()` - a function that does not strip path traversal sequences. This makes it possible for authenticated attackers, with Administrator-level access and above, to list the contents of arbitrary directories on the server outside of the intended uploads directory."}],"title":"Keep Backup Daily <= 2.1.1 - Authenticated (Admin+) Limited Path Traversal via 'kbd_path' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/01984754-e332-4500-99a2-10a7b79967f5?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/keep-backup-daily/tags/2.1.1/inc/functions.php#L855"},{"url":"https://plugins.trac.wordpress.org/browser/keep-backup-daily/trunk/inc/functions.php#L855"},{"url":"https://plugins.trac.wordpress.org/browser/keep-backup-daily/tags/2.1.1/inc/functions.php#L871"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3481587%40keep-backup-daily&new=3481587%40keep-backup-daily&sfp_email=&sfph_mail="}],"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:L/I:N/A:N","baseScore":2.7,"baseSeverity":"LOW"}}],"credits":[{"lang":"en","type":"finder","value":"san6051"}],"timeline":[{"time":"2026-03-20T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-24T13:39:17.921104Z","id":"CVE-2026-3339","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-24T13:39:30.198Z"}}]}}
