What is CVE-2026-0831?
CVE-2026-0831 is a medium-severity path traversal vulnerability in wpdevteam Templately – Elementor & Gutenberg Template Library: 6500+ Free & Pro Ready Templates And Cloud!, published on 10 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-863
