This is due to two compounding flaws: the Members::update() method does not validate or restrict the value of file-type custom profile fields, allowing authenticated users to store an arbitrary path instead of a legitimate upload path; and the wpforo_fix_upload_dir() sanitization function in ucf_file_delete() only remaps paths that match the expected pattern, and it is passed directly to the unlink() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Note: The vulnerability requires a file custom field, which requires the wpForo - User Custom Fields addon plugin."}],"title":"wpForo Forum <= 3.0.5 - Authenticated (Subscriber+) Arbitrary File Deletion via Custom Profile Field File Path","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/79cc102a-6777-41be-a395-8c2eeb6deb73?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/wpforo/classes/Actions.php#L1418"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/wpforo/includes/functions.php#L3187"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/wpforo/classes/Members.php#L891"},{"url":"https://plugins.trac.wordpress.org/changeset/3509997/wpforo"}],"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:L/UI:N/S:U/C:N/I:H/A:H","baseScore":8.1,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Jude Nwadinobi"},{"lang":"en","type":"finder","value":"wackydawg"}],"timeline":[{"time":"2026-04-13T18:36:06.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-04-20T05:51:32.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-21T17:35:14.554882Z","id":"CVE-2026-6248","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":"2026-04-21T17:35:30.317Z"}}]}}
