原文摘录

摘自原文(2145 字符中的一小部分)
Summary: A normal user can create a playbook, that has some attributes like the `run_summary_template`, `retrospective_template` and `description`,that don't have any size check or validation, which allows an attacker to set an unlimited number of characters as their values.
原文中的代码
curl -X POST "http://<domain>/plugins/playbooks/api/v0/playbooks" -H 'Content-Type: application/json' -d @payload --cookie "MMAUTHTOKEN=<user-auth-token>" -H "X-CSRF-TOKEN: <csrf-token>"
