CVE-2026-14270Network attack vector

Subscriber-level RCE via upload allowlist manipulation

Published Jul 29, 2026 · Updated Jul 29, 2026

Arbitrary file upload in ThemeComplete Extra Checkout Options 2.3.2 and earlier allows remote authenticated users to execute PHP code. The eco_save_settings() function accepts Subscriber-level changes to the tc_eco_custom_file_types allowlist without authorization or nonce validation, and wc_eco_upload_file then accepts a PHP file with a frontend upload nonce. Subscriber access and a cart or checkout page exposing that nonce are sufficient to upload server-executable PHP and obtain remote code execution.
