## What is CVE-2026-45404?

CVE-2026-45404 is a medium-severity vulnerability in open-telemetry opentelemetry-go, published on 24 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official 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.

Weakness: CWE-667 (Improper Locking), CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization)

## Which versions are affected by CVE-2026-45404?

3 open source packages ship an affected version, including go.opentelemetry.io/otel/bridge/opentracing.


| Package | Ecosystem | Affected | Fixed in |
| --- | --- | --- | --- |
| `go.opentelemetry.io/otel/bridge/opentracing` | Go | From 0.11.0 | 1.45.0 |
| `go.opentelemetry.io/otel/bridge/opentracing` | Go | From 0.11.0 | 1.45.0 |
| `go.opentelemetry.io/otel/bridge/opentracing` | Go | From 0.11.0 | 1.45.0 |

## How do I fix CVE-2026-45404?

Upgrade go.opentelemetry.io/otel/bridge/opentracing to 1.45.0 or later.

## Is CVE-2026-45404 being exploited?

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-45404 and fix it if it is affected.

What it is: CVE-2026-45404 is a medium-severity vulnerability in open-telemetry opentelemetry-go, published on 24 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45404 exists.

Affected packages and fixed versions:
- go.opentelemetry.io/otel/bridge/opentracing (Go): affected from 0.11.0; fixed in 1.45.0
- go.opentelemetry.io/otel/bridge/opentracing (Go): affected from 0.11.0; fixed in 1.45.0
- go.opentelemetry.io/otel/bridge/opentracing (Go): affected from 0.11.0; fixed in 1.45.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
