Detailsinfo

A vulnerability was found in OpenTelemetry JavaScript up to 0.221.x. It has been rated as problematic. This issue affects an unknown function of the component instrumentation-http. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. The summary by CVE is:

OpenTelemetry JavaScript is the OpenTelemetry JavaScript client. From 0.204.0 until 0.222.0, @opentelemetry/instrumentation-http writes the raw query string from incoming HTTP requests to the url.query server-span attribute without applying the redactedQueryParams protection used for outgoing spans. Services receiving signed URLs or other credentials in query parameters can therefore export still-valid secrets to tracing backends, where observability infrastructure and users with span-read access may read them. The redactedQueryParams option does not protect incoming spans in affected versions. This issue is fixed in version 0.222.0.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-128080 since 11/12/2026. The exploitation is known to be easy.
