CVE-2025-12637Network attack vector

Authenticated arbitrary file upload via dynamic code generation

Published Nov 11, 2025 · Updated Nov 11, 2025

Arbitrary file upload in Elastic Theme Editor 0.0.3 and earlier allows remote authenticated users to write files to the WordPress server. Wordfence identifies dynamic code generation in process_theme as the upload path, but the public record does not disclose the unchecked parameter or file-writing operation. Subscriber-level access is sufficient; executable uploads can result in code execution under the web server account.
