Description
A vulnerability in open-telemetry's JavaScript client (opentelemetry-js) versions 0.204.0 through 0.221.x causes raw query strings from incoming HTTP requests to be recorded in tracing spans without redaction. This can expose sensitive information such as signed URLs or credentials to anyone with access to tracing backends. The issue is fixed in version 0.222.0.
