github.com/open-telemetry/opentelemetry-go: go.opentelemetry.io/otel/baggage: go.opentelemetry.io/otel/propagation: OpenTelemetry-Go: Denial of Service via oversized baggage headers

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...
