CVE-2023-39951

Summary

CVE-2023-39951 affects OpenTelemetry Java Instrumentation versions prior to 1.28.0. This vulnerability stems from the instrumentation of Java applications using the AWS SDK v2 with Amazon Simple Email Service (SES) v1 API. The issue causes query parameters to be inserted into the trace `url.path` field, resulting in the email body, which includes the subject and message, being present in the trace request url metadata. This exposure of email content to unintended audiences can be mitigated by updating to OpenTelemetry Java Instrumentation version 1.28.0 or later. Users of AWS SDK v2 calls to SES’s v1 SendEmail API are vulnerable if they have not yet updated their OpenTelemetry Java Instrumentation.
