Impact	CVSS 9.8, EPSS 66.1%, patch available. WordPress File Upload has 100,000+ installations. The triple vulnerability gives attackers multiple exploitation paths: information disclosure (reading credentials), denial of service (deleting files), and full compromise (RCE).
Exploit ScenarioDerived	An attacker exploits the arbitrary file read to download wp-config.php, obtaining database credentials and secret keys. They use the database credentials to insert a backdoor admin user. If direct database access isn't possible, they use the RCE capability to deploy a webshell. They also delete security plugin files to prevent detection.

AnalysisAIv1 – Mar 28, 2026

The WordPress File Upload plugin through version 4.24.15 contains critical vulnerabilities in wfu_file_downloader.php enabling remote code execution, arbitrary file read, and arbitrary file deletion. The lack of proper sanitization on the source parameter combined with user-defined directory paths allows unauthenticated attackers to fully compromise the server.

v1 Mar 28, 2026 - 18:02 CVSS 9.8

Triple-threat vulnerability in WordPress File Upload plugin: RCE, arbitrary file read, and file deletion via unsanitized source parameter.

RemediationAI

Update to WordPress File Upload 4.24.16 or later. Restrict access to wfu_file_downloader.php at the web server level. Rotate database credentials and WordPress secret keys. Review file system integrity for unauthorized modifications or deletions.

Checking this CVE against your own stacks and servers is part of the Basic plan and up.

Technical ContextAI · show details

The wfu_file_downloader.php file accepts a source parameter that controls file operations without proper sanitization or access controls. An attacker can manipulate this parameter to: (1) read arbitrary files including wp-config.php, (2) delete critical files causing DoS, or (3) achieve code execution by chaining file operations with PHP filter chains or other exploitation techniques. No authentication is required.

CRITICAL 9.8

DescriptionCVE.org

The WordPress File Upload plugin for WordPress is vulnerable to Remote Code Execution, Arbitrary File Read, and Arbitrary File Deletion in all versions up to, and including, 4.24.15 via the 'wfu_file_downloader.php' file. This is due to lack of proper sanitization of the 'source' parameter and allowing a user-defined directory path. This makes it possible for unauthenticated attackers to execute code on the server.

Executive ViewAI

Why It Matters

Organizations using all face critical risk from CVE-2024-11613, a code injection vulnerability rated CVSS 9.8. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. With an EPSS score of 66%, this vulnerability faces very high likelihood of exploitation. A patch is available and should be applied immediately given the critical severity.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.

Attack Technique

Malicious File Upload HIGH

Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
