# CVE-2026-0831: Templately \<= 3.4.8 - Unauthenticated Limited Arbitrary JSON File Write

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-01-10 · Updated: 2026-04-08

## Affected

- wpdevteam Templately – Elementor & Gutenberg Template Library: 6500+ Free & Pro Ready Templates And Cloud!: through 3.4.8

## 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.
