{"id":"CVE-2024-32028","aliases":["GHSA-vh2m-22xx-q94f"],"url":"https://o3.security/vulnerability/CVE-2024-32028","summary":"Sensitive query parameters logged by default in OpenTelemetry.Instrumentation http and AspNetCore","details":"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.","published":"2024-04-12T22:58:30.526Z","modified":"2026-08-12T03:51:22.596572743Z","cvss":{"score":4.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N"},"epss":{"score":0.00291,"percentile":0.21738,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"OpenTelemetry.Instrumentation.Http","fixedVersion":"1.8.1"},{"ecosystem":"NuGet","name":"OpenTelemetry.Instrumentation.AspNetCore","fixedVersion":"1.8.1"}],"fix":{"url":"https://github.com/open-telemetry/opentelemetry-dotnet/commit/e222ecb5942d4ce1cadfd4306c39e3f4933a5c42","label":"open-telemetry/opentelemetry-dotnet@e222ecb"},"references":[{"type":"WEB","url":"https://github.com/open-telemetry/semantic-conventions/blob/main/docs/http/http-spans.md"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/32xxx/CVE-2024-32028.json"},{"type":"ADVISORY","url":"https://github.com/open-telemetry/opentelemetry-dotnet/security/advisories/GHSA-vh2m-22xx-q94f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-32028"},{"type":"FIX","url":"https://github.com/open-telemetry/opentelemetry-dotnet/commit/e222ecb5942d4ce1cadfd4306c39e3f4933a5c42"},{"type":"PACKAGE","url":"https://github.com/open-telemetry/opentelemetry-dotnet"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:22.596572743Z"}}
