CyberRota Analysis
AI-GeneratedThe vulnerability affects the attachment upload tools in Jira and Confluence, allowing attackers to exploit arbitrary local filesystem paths and potentially disclose sensitive files, including configuration and credentials, from the server. This poses a significant risk in environments with HTTP or multi-user deployments, where unauthorized access to critical data could occur. Organizations using affected versions of these Atlassian products should prioritize upgrading to version 0.22.0 to mitigate this high-severity risk.

Original NVD Description
MCP Atlassian is a Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira). Prior to 0.22.0, Jira and Confluence attachment upload tools accept arbitrary local filesystem paths and send the selected bytes to Atlassian. In HTTP or multi-user deployments, a caller can cross the client-to-server filesystem boundary and disclose configuration, credentials, mounted secrets, or other files readable by the MCP process. The advisory traces the vulnerable input and processing flow through jira_upload_attachment, confluence_upload_attachment, file_path, and server-local filesystem, which identify the affected entry points, controls, and code paths. This issue is fixed in version 0.22.0.
