Summary

CVE-2025-3515 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Codedropz Drag And Drop Multiple File Upload - Contact Form 7. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The Drag and Drop Multiple File Upload for Contact Form 7 plugin for WordPress is affected by CVE-2025-3515, an arbitrary file upload vulnerability stemming from insufficient file type validation. All versions through 1.3.8.9 are impacted, enabling bypass of the plugin's blacklist to upload files such as .phar that can be treated as executable PHP under certain server configurations.

Unauthenticated attackers can exploit the flaw remotely with no user interaction required. Successful exploitation allows upload of dangerous file types to the site server, which may result in remote code execution on systems where the web server passes .phar extensions to the PHP interpreter without strict validation, such as default Apache plus mod_php setups.

Public references point to the vulnerable code in the plugin repository, a subsequent changeset that addresses the issue, and a detailed Wordfence threat advisory that outlines the affected component and remediation path through plugin updates.

EPSS for the CVE rose from lower values to a peak of 0.0602 on 2026-04-13 before receding to the current 0.0370, indicating measurable post-disclosure exploitation interest.

Vulnerability Data

The Drag and Drop Multiple File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in all versions up to, and including, 1.3.8.9. This makes it possible for unauthenticated…

more

attackers to bypass the plugin's blacklist and upload .phar or other dangerous file types on the affected site's server, which may make remote code execution possible on the servers that are configured to handle .phar files as executable PHP scripts, particularly in default Apache+mod_php configurations where the file extension is not strictly validated before being passed to the PHP interpreter.

Mitigating Controls (NIST 800-53 r5) AI

SI-3 Malicious Code Protection good match

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

CM-7 Least Functionality partial match

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-05 mostly match
prevents

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce allowed file types and processing rules.

PR.PS-06 partial match
prevents

Secure development practices include input validation and file-type restrictions that prevent this weakness.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

A.8.25 Secure development life cycle partial match
prevents

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.

A.8.30 Outsourced development partial match
prevents

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.

A.8.7 Protection against malware partial match
mitigates

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.
