Title
OpenTelemetry JavaScript: Denial of service in `JaegerPropagator` via unhandled exception on a malformed header
Summary
OpenTelemetry JavaScript is the OpenTelemetry JavaScript client. Prior to 2.9.0, @opentelemetry/propagator-jaeger decodes incoming uber-trace-id and uberctx-* HTTP header values with decodeURIComponent() without handling decode errors, allowing an unauthenticated remote attacker to send a malformed percent-encoded value that throws an uncaught URIError and terminates a Node.js process using JaegerPropagator as the active propagator. This issue is fixed in version 2.9.0.

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.

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.
