Vulnerability from github – Published: 2026-01-10 12:30 – Updated: 2026-01-10 12:30

Details

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.

Severity ?
5.3 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
