OpenTelemetry dotnet is a dotnet telemetry framework. In affected versions of OpenTelemetry.Instrumentation.Http and OpenTelemetry.Instrumentation.AspNetCore the url.full writes attribute/tag on spans (Activity) when tracing is enabled for outgoing http requests and OpenTelemetry.Instrumentation.AspNetCore writes the url.query attribute/tag on spans (Activity) when tracing is enabled for incoming http requests. These attributes are defined by the Semantic Conventions for HTTP Spans. Up until version 1.8.1 the values written by OpenTelemetry.Instrumentation.Http & OpenTelemetry.Instrumentation.AspNetCore will pass-through the raw query string as was sent or received (respectively). This may lead to sensitive information (e.g. EUII - End User Identifiable Information, credentials, etc.) being leaked into telemetry backends (depending on the application(s) being instrumented) which could cause privacy and/or security incidents. Note: Older versions of OpenTelemetry.Instrumentation.Http & OpenTelemetry.Instrumentation.AspNetCore may use different tag names but have the same vulnerability. The 1.8.1 versions of OpenTelemetry.Instrumentation.Http & OpenTelemetry.Instrumentation.AspNetCore will now redact by default all values detected on transmitted or received query strings. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-32028
This medium-severity CVE scores 4.1 under NVD CVSS v3. EPSS exploit probability: 0.0%, top 87% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
