CVE-2025-12677Network attack vectorHinoki check available

Unauthenticated webhook token disclosure via API route

Published Nov 5, 2025 · Updated Nov 5, 2025

Sensitive information exposure in KiotViet Sync 1.8.5 and earlier allows remote attackers to read a configured webhook token. The register_api_route() function in kiotvietsync/includes/public_actions/WebHookAction.php exposes the token through a WordPress API route without requiring authentication. The route yields the token only when webhook integration is configured, limiting the consequence to disclosure of that reusable secret.
