Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-11456 is an arbitrary file upload vulnerability in the ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress, affecting all versions up to and including 3.3.1. The flaw stems from missing file type validation in the eh_crm_new_ticket_post() function, enabling attackers to upload arbitrary files to the affected site's server. It is classified under CWE-434 and carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no user interaction required. By leveraging the flawed ticket submission function, they can upload malicious files, such as web shells, potentially leading to remote code execution on the server.
Advisories and references, including Wordfence threat intelligence and WordPress plugin repository sources, point to the vulnerable code in class-crm-ajax-functions-three.php and a related changeset (3399391). Mitigation involves updating the plugin to a patched version beyond 3.3.1, as indicated by the version scope in the CVE description.

V5.1.1
Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Hardened configuration baselines can enforce allowed file types and processing rules.
Secure development practices include input validation and file-type restrictions that prevent this weakness.

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.
Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.
Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
