CVE-2026-45404
OpenTelemetry-Go is the Go implementation of OpenTelemetry.
Overview
CVE-2026-45404 is a known-severity vulnerability. It was published on August 24, 2026.
Technical description
OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 0.11.0 through 1.44.0, the OpenTracing bridge's bridgeSpan contains an unsynchronized extraBaggageItems map which can cause a panic. Because Go maps are not safe for concurrent read/write access, concurrent SetBaggageItem and correlation.MapFromContext calls on the same hooked bridgeSpan can trigger a fatal runtime error—such as concurrent map read and map write or concurrent map iteration and map write—terminating the process and causing denial of service. This issue is fixed in version 1.45.0.

How can CyberStrike help with CVE-2026-45404?
CyberStrike is an open-source, AI-augmented pentesting engine.
