CVE-2026-93754 Details
Description
The payever – WooCommerce Gateway plugin for WordPress is vulnerable to arbitrary file upload leading to remote code execution in various versions up to, and including, 4.8.0. Three WooCommerce-API callbacks (payever_set_sandbox_api_keys, payever_toggle_subscription, payever_synchronization_incoming) are registered with no authentication, capability check, or nonce, and the upload_image() routine writes a remotely fetched file to the public uploads directory using an attacker-controlled basename() BEFORE validating the file type. This makes it possible for unauthenticated attackers to write an executable PHP file and achieve remote code execution. NOTE: the token-recovery leg of the full chain depends on the plugin's outbound validateToken() call to Payever's service; the unauthenticated hard-coded-credential identity overwrite (CWE-862/CWE-798) is independently exploitable.
A vulnerability allowing arbitrary file upload has been identified in the Payever WooCommerce Gateway plugin for WordPress, affecting versions through 4.8.0. The issue arises from three WooCommerce-API callbacks that lack authentication, capability checks, and nonces. The vulnerability allows unauthenticated attackers to upload executable PHP files to the public uploads directory, which can then be executed remotely, leading to code execution on the server.
Users are advised to update the Payever WooCommerce Gateway plugin to version 4.9.0 or later.
