{"cve":"CVE-2026-6248","nvd":{"published":"2026-04-20T19:16:11.230","modified":"2026-06-17T11:00:32.480","status":"Deferred","description":"The wpForo Forum plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to and including 3.0.5. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-22"],"references":["https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/wpforo/classes/Actions.php#L1418","https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/wpforo/classes/Members.php#L891","https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/wpforo/includes/functions.php#L3187","https://plugins.trac.wordpress.org/changeset/3509997/wpforo","https://www.wordfence.com/threat-intel/vulnerabilities/id/79cc102a-6777-41be-a395-8c2eeb6deb73?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-6248","score":0.00593,"percentile":0.48367,"date":"2026-11-01"},"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).
