Title
podinfo 6.11.2 Reflected XSS via /echo Endpoint
Summary
podinfo through 6.11.2 contains a reflected cross-site scripting vulnerability in the /echo and /api/echo endpoints where the echoHandler writes request body content directly to the response without setting explicit Content-Type or X-Content-Type-Options headers. Attackers can craft cross-origin HTML pages with auto-submitting forms containing script payloads in the request body, which are served as text/html due to Go's content type detection, allowing the reflected script to execute in the podinfo origin context when victims visit the attacker's page.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
