Administrators, editors, or any user with Author role can exploit the flaw.\n", "description_and_impact": "The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable because the functions WPUF_Admin_Settings::check_filetype_and_ext and Admin_Tools::check_filetype_and_ext perform incorrect file type validation. This allows an authenticated user with Author-level permissions or higher to upload arbitrary files to the server. By uploading a malicious file such as a PHP script or web shell, a threat actor can potentially execute code on the system. The flaw is classified as CWE-434, uncategorized file upload.\n", "risk_and_exploitability": "The CVSS score of 8.8 indicates a high severity vulnerability, while the EPSS score of less than 1% suggests a very low probability of exploitation at the time of analysis. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires only that an attacker obtain Author-level or higher access to the site, a privilege level commonly granted to site contributors. The attacker can then use the plugin\u2019s upload interface to place a crafted file onto the server, potentially leading to remote code execution. The attack vector is likely local through the WordPress admin interface and does not require external network exposure.\n"}}}}, "created": "2026-02-27T09:07:07.406601+00:00", "updated": "2026-04-15T20:15:13.722169+00:00", "vendors": ["wedevs", "wedevs$PRODUCT$user_frontend:_ai_powered_frontend_posting,_user_directory,_profile,_membership_&_user_registration", "wordpress", "wordpress$PRODUCT$wordpress"]}
