CVE-2026-0831Network attack vector

Unauthenticated JSON file write via unsanitized paths

Published Jan 10, 2026 · Updated Jan 10, 2026

Arbitrary file write in WPDeveloper Templately 3.4.8 and earlier allows remote attackers to write .ai.json files under uploads. The unauthenticated AI content API passes user-controlled session_id, content_id, and ai_page_ids into save_template_to_file(), which constructs destination paths without sanitizing those path components. The write is limited to .ai.json files within the WordPress uploads tree, so the demonstrated consequence is unauthorized file creation rather than code execution.
