MEDIUMCVSS 5.8/10

Last modified

CVE-2026-128080 is a medium-severity vulnerability rated 5.8/10 on the CVSS scale. 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.

Description

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.
