Security Impact
CVSS: 7.2
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-12476
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-12476, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"details" : "The Easy Digital Downloads plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to and including 3.6.9. This is due to insufficient file type validation in the edd_do_ajax_import_file_upload() function , which only checks the client-supplied $_FILES['edd-import-file']['type'] Content-Type header against an allow-list of CSV mime types, then uses raw move_uploaded_file() (bypassing wp_handle_upload()'s core MIME enforcement) to write the file under its original extension into the web-accessible wp-content/uploads/edd/exports/ directory. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.",
