NewCVE-2026-45404 Â (opens in a new tab)How to fix?
Upgrade github.com/open-telemetry/opentelemetry-go/bridge/opentracing to version 1.45.0 or higher.
Overview
Affected versions of this package are vulnerable to Improper Locking through the bridgeSpan baggage handling in bridge/opentracing/bridge.go. An attacker can crash the process by causing one goroutine to call Span.SetBaggageItem while another goroutine propagates correlation baggage from the same span via baggageGetHook. This affects applications using the OpenTelemetry OpenTracing bridge with correlation hooks, where unsynchronized reads, iteration, and writes to extraBaggageItems can trigger Go's fatal concurrent map read and map write or concurrent map iteration and map write panic.
