{"cve":"CVE-2023-39951","nvd":{"published":"2023-08-08T22:15:10.827","modified":"2026-06-17T06:13:00.977","status":"Modified","description":"OpenTelemetry Java Instrumentation provides OpenTelemetry auto-instrumentation and instrumentation libraries for Java. OpenTelemetry Java Instrumentation prior to version 1.28.0 contains an issue related to the instrumentation of Java applications using the AWS SDK v2 with Amazon Simple Email Service (SES) v1 API. When SES POST requests are instrumented, the query parameters of the request are inserted into the trace `url.path` field. This behavior leads to the http body, containing the email subject and message, to be present in the trace request url metadata. Any user using a version before 1.28.0 of OpenTelemetry Java Instrumentation to instrument AWS SDK v2 call to SES’s v1 SendEmail API is affected. The e-mail content sent to SES may end up in telemetry backend. This exposes the e-mail content to unintended audiences. The issue can be mitigated by updating OpenTelemetry Java Instrumentation to version 1.28.0 or later.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/open-telemetry/opentelemetry-java-instrumentation/issues/8956","https://github.com/open-telemetry/opentelemetry-java-instrumentation/pull/8931","https://github.com/open-telemetry/opentelemetry-java-instrumentation/security/advisories/GHSA-hghr-r469-gfq6","https://github.com/open-telemetry/opentelemetry-java-instrumentation/issues/8956","https://github.com/open-telemetry/opentelemetry-java-instrumentation/pull/8931"],"products":["linuxfoundation:opentelemetry_instrumentation_for_java"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-39951","score":0.00836,"percentile":0.57759,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
