CVE-2026-9067: CWE-434 Unrestricted Upload of File with Dangerous Type in Schema & Structured Data for WP & AMP
The Schema & Structured Data for WP & AMP WordPress plugin before version 1. 60 contains a vulnerability that allows unauthenticated users to upload files of any type accepted by WordPress's media library through frontend AJAX endpoints intended only for images or videos. This occurs because the plugin does not verify user capabilities nor validate the actual content type of uploaded files. No patch or official remediation guidance is currently provided.
AI Analysis
Technical Summary
CVE-2026-9067 is a vulnerability in the Schema & Structured Data for WP & AMP WordPress plugin prior to version 1.60. The issue arises from missing user capability checks on frontend AJAX file-upload handlers and lack of validation of uploaded file content against the expected media type. This flaw permits unauthenticated attackers to upload arbitrary file types through endpoints that should restrict uploads to images or videos, potentially enabling malicious file uploads.
Potential Impact
Unauthenticated users can upload any file type accepted by WordPress's media library via endpoints that should only accept images or videos. This could lead to unauthorized file uploads, which may be leveraged for further attacks depending on the server configuration and file handling policies. The exact impact depends on how uploaded files are processed or accessed but includes risk of arbitrary file upload.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected AJAX upload endpoints or disable the plugin's frontend upload functionality if possible to prevent unauthorized uploads.
