Deeper analysis
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
