Swarm Plugin adds API endpoints to add or remove agent labels. In Swarm Plugin 3.20 and earlier these only require a global Swarm secret to use, and no regular permission check is performed. This allows users with Agent/Create permission to add or remove labels of any agent.
Additionally, these API endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Swarm Plugin 3.21 requires POST requests and Agent/Configure permission for the affected agent to these endpoints. It no longer uses the global Swarm secret for these API endpoints.
