Prior to 0.22.0, the confluence_upload_attachment and confluence_upload_attachments tools pass a client-controlled file_path through src/mcp_atlassian/confluence/attachments.py upload_attachment, and the jira_update_issue attachments parameter reaches src/mcp_atlassian/jira/attachments.py upload_attachment, without confining either path to an approved server workspace. In a remote HTTP, SSE, or multi-user deployment, absolute or traversing paths are resolved on the MCP server and uploaded to Atlassian, allowing a client with write-tool access to disclose server files, environment-held Atlassian credentials, or another tenant&#39;s data. A local single-user stdio deployment does not cross this trust boundary because the server runs in the caller&#39;s environment. This issue is fixed in version 0.22.0.</p> <p><strong>Affected:</strong> sooperset mcp-atlassian</p> <p>MCP Atlassian is a Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira).
