0 CVE-2026-27826 is a high-severity Server-Side Request Forgery (SSRF) vulnerability in sooperset's mcp-atlassian server versions prior to 0.17.0. It allows unauthenticated attackers who can access the HTTP endpoint to force the server to make arbitrary outbound HTTP requests by supplying two custom headers without needing an Authorization header. This vulnerability resides in the HTTP middleware and dependency injection layer, bypassing tool-level code detection. In cloud environments, it can lead to theft of IAM role credentials via the instance metadata service. In any deployment, it enables internal network reconnaissance and injection of attacker-controlled content into LLM tool results. The issue is fixed in version 0.17.0.
