An issue in Jumpserver before 2.6.2, before 2.5.4, before 2.4.5 allows attackers to create a connection token through an API which does not have access control and use it to access sensitive assets.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
