1.45.0· Vendor fix available
Issue
OpenTelemetry Go versions 1.5.0 through 1.44.0 can include trace exporter endpoint configuration in an internal diagnostic log emitted when an SDK TracerProvider is created. The default OpenTelemetry logger does not emit this event. Exposure requires an application to install a logger that enables OpenTelemetry's internal Info-level diagnostics and for someone other than the intended audience to have access to those logs. The logged configuration can disclose the address of the trace collector and whether the OTLP/HTTP connection is configured as insecure. The Zipkin exporter logs its complete collector URL, so credentials in URL userinfo or tokens in the query string are also disclosed if an application embeds them there. OTLP authentication headers, TLS key material, and exported span data are not included in this log. Exporter MarshalLog implementations that caused this configuration to be included in internal logs were introduced by a1fff3c. Details When…

Go go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp < 1.43.0
Fixed in
1.43.0· Vendor fix available
Issue
this report shows that the otlp HTTP exporters (traces/metrics/logs) read the full HTTP response body into an in-memory bytes.Buffer without a size cap. this is exploitable for memory exhaustion when the configured collector endpoint is attacker-controlled (or a network attacker can mitm the exporter connection). severity HIGH not claiming: this is a remote dos against every default deployment. claiming: if the exporter sends traces to an untrusted collector endpoint (or over a network segment where mitm is realistic), that endpoint can crash the process via a large response body. callsite (pinned): - exporters/otlp/otlptrace/otlptracehttp/client.go:199 - exporters/otlp/otlptrace/otlptracehttp/client.go:230 - exporters/otlp/otlpmetric/otlpmetrichttp/client.go:170 - exporters/otlp/otlpmetric/otlpmetrichttp/client.go:201 - exporters/otlp/otlplog/otlploghttp/client.go:190 - exporters/otlp/otlplog/otlploghttp/client.go:221 permalinks (pinned): -…
