GitLab MCP Server < 2.1.27 - Unauthenticated SSE Transport Access

The @zereight/mcp-gitlab GitLab MCP server exposes its SSE transport endpoints without any authentication when SSE mode is enabled. An unauthenticated attacker with network access can establish an MCP session and invoke every registered tool, including uploadmarkdown, which reads arbitrary files...

PYSEC-2026-4109 MySQL MCP Server: Missing Origin/Host Validation in SSE Transport Enables Unauthenticated SQL Execution (DNS Rebinding / Direct Exposure)

Summary In SSE/HTTP transport mode, mysqlmcpserver constructs SseServerTransport without passing securitysettings. As a result, the MCP Python SDK's DNS-rebinding protection Origin/Host header validation is disabled; the Starlette application has no CORS or TrustedHost middleware; and the service...

CVE-2026-61593

djust (a Phoenix LiveView-style reactive server-side rendering library for Django with Rust) is vulnerable to Cross-Site Request Forgery (CSRF) on its Server-Sent Events (SSE) transport prior to version 1.0.7 . The root cause: SSE POST endpoints were @csrf_exempt, the SSE GET stream endpoint lack...

CVE-2026-61593 djust has Cross-Site Request Forgery on the Server-Sent-Events transport: a cross-origin page can drive a victim-authenticated SSE session

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, the SSE client→server POST endpoints are @csrfexempt and the SSE GET stream endpoint had no Origin check, so a cross-origin page could drive a...

djust has Cross-Site Request Forgery on the Server-Sent-Events transport: a cross-origin page can drive a victim-authenticated SSE session

Impact The SSE client→server POST endpoints are @csrfexempt and the SSE GET stream endpoint had no Origin check, so a cross-origin page could drive a victim-cookie-authenticated SSE session: force the victim's browser to GET the stream URL which creates and mounts a LiveView as the victim and POS...
