PYSEC-2026-4095 MCP Atlassian: Path traversal in upload_attachment allows arbitrary file read (incomplete fix for CVE-2026-27825)

Summary The confluenceuploadattachment and confluenceuploadattachments MCP tools accept a filepath parameter and do not validate that the path is confined to an allowed directory before opening the file. An attacker who can call these tools can read any file accessible to the MCP server process S...

MCP Atlassian: Path Traversal / Arbitrary File Read in confluence_upload_attachment MCP tool (incomplete fix of GHSA-xjgw-4wvw-rgm4)

Summarymcp-atlassian exposes an MCP tool confluenceuploadattachment whose filepath argument is passed directly to openfilepath, "rb" without any path validation. An attacker able to invoke the tool can read arbitrary files readable by the server process and exfiltrate them into a multipart upload...

PYSEC-2026-4101 MCP Atlassian: Jira and Confluence attachment upload tools can read arbitrary server-local files

Summary MCP Atlassian exposes Jira and Confluence attachment upload tools that accept arbitrary local filesystem paths and upload those file contents to Atlassian. In HTTP or multi-user deployments, an MCP caller who can invoke write tools can cause the server to read any file accessible to the M...

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

SummaryThe 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 reco...

MCP Atlassian: Unauthenticated arbitrary local file read via upload_attachment file_path, chained with missing auth on streamable-http transport

SummaryIn the documented multi-user HTTP deployment --transport streamable-http with global operator Atlassian credentials, sooperset/mcp-atlassian exposes all tools to unauthenticated network clients, and the uploadattachment tool reads an attacker-supplied filepath with no path validation...

MCP Atlassian: MCP HTTP Client Server-Local File Exfiltration via Unvalidated Attachment Upload Path

SummaryThe mcp-atlassian server exposes an MCP tool confluenceuploadattachment and the Jira attachment variant that accepts an arbitrary server-side file path and opens it for upload without any path validation.

foreman-mcp-server Inserts Sensitive Information into Log File

A flaw was found in foreman-mcp-server. This component utilizes two distinct logging mechanisms that can expose sensitive session and authentication data. One mechanism logs session identifiers, which are treated as authentication credentials, at an informational level. The other, when debug...

Apache Doris MCP Server is vulnerable to SQL Injection via metadata query path

Apache Doris MCP Server contains a SQL injection vulnerability in a metadata query path. A user-controlled database name is directly interpolated into a SQL query, and the query is executed without passing the caller's authorization context. This may allow an authenticated attacker, or an anonymo...
