CyberRota Analysis
AI-GeneratedThe Model Context Protocol (MCP) server for Atlassian products, including Confluence and Jira, is vulnerable due to improper user identity verification, allowing unauthorized network clients to perform actions as the operator using their credentials. This critical vulnerability could lead to unauthorized read and write access to sensitive data within these applications. Organizations using versions prior to 0.22.0 should prioritize immediate updates to mitigate the risk of exploitation.

Original NVD Description
MCP Atlassian is a Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira). Prior to 0.22.0, the HTTP transport accepts requests without a verified user identity and downstream fetcher construction falls back to the operator's globally configured Jira or Confluence credentials. A network client that can reach the MCP endpoint can invoke Atlassian tools as the operator, including read and write operations available to that account. The advisory traces the vulnerable input and processing flow through UserTokenMiddleware, AtlassianOpaqueTokenVerifier, _get_fetcher, and streamable-http, which identify the affected entry points, controls, and code paths. This issue is fixed in version 0.22.0.
