Vulnerability details
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to SQL injection in create_all_header_nodes() in lib/api_automation.php when processing a stored field value from automation_tree_rule_items.field during automation rule execution. A remote privileged user can store a crafted SQL fragment that is later executed to disclose sensitive information.
