OpenTelemetry-Go: Log gRPC exporter ignores env TLS certs, bypassing mTLS/pinning

Summary The OTLP log gRPC exporter loads TLS settings from environment variables but does not apply them when creating gRPC transport credentials. Operators who rely on OTELEXPORTEROTLPLOGSCERTIFICATE, OTELEXPORTEROTLPCERTIFICATE, or related client certificate variables for CA pinning or mTLS get...

OpenTelemetry-Go: Exporter config logging may leak endpoint URLs in info logs

Summary 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 tha...

go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc: OpenTelemetry-Go: TLS certificate bypass allows log telemetry interception and alteration

A flaw was found in OpenTelemetry-Go, specifically within its gRPC log exporter. This vulnerability allows a network attacker to bypass the intended private Certificate Authority CA pinning and mutual Transport Layer Security TLS configurations. The issue arises because the environment-only TLS...

go.opentelemetry.io/otel/sdk/log: OpenTelemetry-Go: Denial of Service via attacker-driven log emission

A flaw was found in the OpenTelemetry-Go BatchingProcessor component. A remote attacker can exploit this by sending a high volume of log emissions, which can fill the asynchronous export buffer. This causes the processor to enter a tight CPU loop, repeatedly retrying to export logs without proper...

A flaw was found in OpenTelemetry-Go. This vulnerability allows a remote attacker to cause a Denial of Service DoS by sending oversized or invalid baggage headers. The Parse function, in affected versions, failed to reject raw-length inputs, leading to excessive processing and error logging when...

Improper Handling of Unicode Encoding

Overview Affected versions of this package are vulnerable to Improper Handling of Unicode Encoding in the attribute truncation process. An attacker can cause the retention of attribute values exceeding the configured length limit by supplying specially crafted Unicode replacement characters,...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the BatchingProcessor. An attacker can exhaust CPU resources and degrade or deny service by continuously filling the asynchronous export buffer while the exporter is backpressured...
