No authentication is required. The vulnerability exists in the HTTP middleware and dependency injection layer — not in any MCP tool handler - making it invisible to tool-level code analysis. In cloud deployments, this could enable theft of IAM role credentials via the instance metadata endpoint (`169.254.169.254`). In any HTTP deployment it enables internal network reconnaissance and injection of attacker-controlled content into LLM tool results.", "references": [ { "reference_url": "https://github.com/sooperset/mcp-atlassian", "reference_id": "", "reference_type": "", "scores": [], "url": "https://github.com/sooperset/mcp-atlassian" }, { "reference_url": "https://github.com/sooperset/mcp-atlassian/commit/5cd697dfce9116ef330b8dc7a91291640e0528d9", "reference_id": "", "reference_type": "", "scores": [], "url": "https://github.com/sooperset/mcp-atlassian/commit/5cd697dfce9116ef330b8dc7a91291640e0528d9" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2026-27826", "reference_id": "CVE-2026-27826", "reference_type": "", "scores": [], "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-27826" }, { "reference_url": "https://github.com/advisories/GHSA-7r34-79r5-rcc9", "reference_id": "GHSA-7r34-79r5-rcc9", "reference_type": "", "scores": [], "url": "https://github.com/advisories/GHSA-7r34-79r5-rcc9" }, { "reference_url": "https://github.com/sooperset/mcp-atlassian/security/advisories/GHSA-7r34-79r5-rcc9", "reference_id": "GHSA-7r34-79r5-rcc9", "reference_type": "", "scores": [], "url": "https://github.com/sooperset/mcp-atlassian/security/advisories/GHSA-7r34-79r5-rcc9" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/74600?format=api", "purl": "pkg:pypi/mcp-atlassian@0.17.0", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/mcp-atlassian@0.17.0" } ], "aliases": [ "CVE-2026-27826", "GHSA-7r34-79r5-rcc9" ], "risk_score": null, "exploitability": null, "weighted_severity": null, "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-71tj-e735-67hd" }, { "url": "http://public2.vulnerablecode.io/api/vulnerabilities/50805?format=api", "vulnerability_id": "VCID-g7ba-7hq5-1bbp", "summary": "MCP Atlassian has an arbitrary file write leading to arbitrary code execution via unconstrained download_path in confluence_download_attachment\nThe `confluence_download_attachment` MCP tool accepts a `download_path` parameter that is written to without any directory boundary enforcement. An attacker who can call this tool and supply or access a Confluence attachment with malicious content can write arbitrary content to any path the server process has write access to.
