CyberRota Analysis
AI-GeneratedThe Templately plugin for WordPress is vulnerable to Remote Code Execution due to improper filename validation in the fetch_remote_file function, allowing authenticated users with contributor-level access or higher to execute arbitrary code on the server. This vulnerability arises from the plugin's reliance on the attacker-controlled Content-Disposition header for file type validation, enabling the upload of malicious files disguised as legitimate image types. WordPress site administrators using this plugin should prioritize patching this vulnerability to prevent potential exploitation and maintain the security of their sites.

Original NVD Description
The Templately – Elementor & Gutenberg Template Library: 6500+ Free & Pro Ready Templates And Cloud! plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 3.7.1 via the fetch_remote_file function. This is due to a filename validation/destination mismatch in fetch_remote_file, where file type validation is performed against the attacker-controlled Content-Disposition filename rather than the URL-path-derived destination filename. This makes it possible for authenticated attackers, with contributor-level access and above, to execute code on the server. A GIF+PHP polyglot file passes wp_check_filetype_and_ext validation as image/gif via the Content-Disposition filename, while the actual destination path is written with a .php extension derived from the URL path, bypassing the unfiltered_upload capability gate entirely. The affected endpoints are reachable at this privilege level because Templately's entire REST API — including the cloud import endpoints used in this attack (/templately/v1/clouds/upload and /templately/v1/insert) — is authorized only by a current_user_can('delete_posts') check, with no administrator or manage_options capability requirement. The same permission gate also allows a contributor to overwrite the site's global Templately cloud connection via the /templately/v1/login endpoint with global_signin set to true. A complete remediation should both correct fetch_remote_file to validate the file type against the actual destination filename rather than the Content-Disposition header (and avoid deriving the write path from the request URL), and restrict state-changing Templately REST routes to an appropriate administrator-level capability.
