Kados R10 GreenBee SQL Injection via update_release.php

Kados R10 GreenBee contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the release_id parameter of boards_buttons/update_release.php. The release_id value is concatenated directly into SQL statements without sanitization, allowing attackers to send a crafted GET request with a UNION-based payload to extract sensitive database information including the current user, database name, and DBMS version.
