CVE-2025-12682
Published: 04 November 2025
Summary
CVE-2025-12682 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 25.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-12682 affects the Easy Upload Files During Checkout plugin for WordPress in all versions up to and including 2.9.8. The vulnerability stems from missing file type validation in the 'file_during_checkout' function, enabling arbitrary JavaScript file uploads. This flaw, classified under CWE-434 (Unrestricted Upload of File with Dangerous Type), 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 due to its potential for high-impact exploitation.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By uploading arbitrary JavaScript files to the affected site's server during the checkout process, attackers may achieve remote code execution, compromising confidentiality, integrity, and availability of the targeted WordPress installation.
Mitigation details are available in advisories from Wordfence and the WordPress plugin trac repository. The trac changeset 3384711 documents the patch implementation, while the Wordfence threat intelligence page provides further vulnerability analysis and recommendations for affected users. Security practitioners should update to a patched version beyond 2.9.8 and review server configurations for uploaded file handling.
