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...

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...

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...

@zereight/mcp-gitlab: Unauthenticated arbitrary file read via `upload_markdown` enables PAT exfiltration and full account takeover

Summary The SSE transport mode SSE=true exposes all MCP tools without any authentication. The uploadmarkdown tool reads arbitrary files from the server's local filesystem via an unsanitized filepath parameter and uploads them to a GitLab project. Combined, any unauthenticated network-reachable...
