The Netic User Export add-on before 2.0.6 for Atlassian Jira does not perform authorization checks. This might allow an unauthenticated user to export all users from Jira by making an HTTP request to the affected endpoint.
CWE-862 - Missing Authorization
The missing authorization vulnerability occurs when a software program allows users to access privileged parts of the program without verifying the user credentials. Impact of such a vulnerability depends on the resources employed by the software, ranging from account takeover to sensitive information exposure, denial of service, and complete system takeover.
