Published Oct 22, 2025 · Updated Oct 22, 2025

Unrestricted file upload in CMSSuperHeroes Clanora before 1.3.1 allows remote attackers to place arbitrary files on WordPress servers. Published advisories identify missing file-type validation in the theme's upload handling but do not disclose the affected endpoint or function. No authentication or user interaction is required, and an uploaded server-executable file enables code execution under the web application's privileges.
