CVE-2026-87935 Details
Description
The Paid Downloads plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.15 via the admin_request_handler function. This is due to missing authorization and file type validation in the admin_request_handler function, which is reachable unauthenticated via is_admin() returning true for /wp-admin/admin-post.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. On Apache servers where AllowOverride is enabled, an .htaccess file placed in the upload directory may block direct HTTP retrieval of uploaded files, limiting exploitability to stacks that do not honor .htaccess directives such as nginx, LiteSpeed, and Apache with AllowOverride None.
A vulnerability allowing arbitrary file upload has been identified in the Paid Downloads plugin for WordPress, affecting all versions through 3.15. The issue arises in the admin_request_handler function, which lacks proper authorization and file type validation. This function can be accessed unauthenticated via wp-admin/admin-post.php, allowing attackers to upload potentially executable files, leading to remote code execution. On Apache servers with AllowOverride enabled, an .htaccess file in the upload directory could block direct access to uploaded files, reducing the vulnerability's impact on servers that do not respect .htaccess, such as nginx or LiteSpeed.
No known patch is available. It is recommended to review the vulnerability details and consider uninstalling the affected plugin.
