This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Templately plugin for WordPress is vulnerable to Arbitrary File Write in all versions up to, and including, 3.4.8. This is due to inadequate input validation in the `save_template_to_file()` function where user-controlled parameters like `session_id`, `content_id`, and `ai_page_ids` are used to construct file paths without proper sanitization. This makes it possible for unauthenticated attackers to write arbitrary `.ai.json` files to locations within the uploads directory.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
