MCP Atlassian: Arbitrary File Read via Upload Attachment Tools

Summary The upload attachment tools in both Confluence and Jira accept arbitrary file paths without path traversal validation. The uploadattachment methods read any file accessible to the server process and upload it to a Confluence page or Jira issue. Despite the existence of a validatesafepath...

MCP Atlassian: SSRF via DNS Rebinding in Header-Based Authentication Flow

Summary The SSRF protection for header-based authentication uses a validate-then-use pattern vulnerable to DNS rebinding. validateurlforssrf resolves the hostname via DNS and checks that the resolved IP is globally routable. However, the actual HTTP request happens later, during which the DNS...

MCP Atlassian: Path traversal in upload_attachment allows arbitrary file read and exfiltration via MCP tool call
