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...

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...
