OpenTelemetry Python: Unbounded tracestate parsing in opentelemetry-api
Summary TraceState.fromheader splits the inbound W3C tracestate header with a regular expression that starts with an unbounded optional-whitespace run, and no length limit is applied first. A run of spaces or tabs that is not followed by a comma costs ON² CPU. A single unauthenticated request wit...
