In versions 1.15.2 and earlier, the Zipkin exporter remote endpoint cache accepts unbounded key growth derived from span attributes. In high-cardinality scenarios, a process using Zipkin export for client or producer spans could experience avoidable memory growth under sustained unique remote endpoint values, increasing process memory usage over time and degrading availability. This issue is fixed in version 1.15.3, which introduces a bounded, thread-safe LRU cache for remote endpoints with a fixed maximum size.","state":0,"publishedAt":"2026-05-06T22:16:25.643+00:00","modifiedAt":"2026-06-17T10:46:29.013+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/open-telemetry/opentelemetry-dotnet/pull/7081","https://github.com/open-telemetry/opentelemetry-dotnet/security/advisories/GHSA-88hf-wf7h-7w4m"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41310","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-400","CWE-770"],"productCriteria":["cpe:2.3:a:opentelemetry:opentelemetry.exporter.zipkin:*:*:*:*:*:.net:*:*"],"sourceDates":{"published":"2026-05-06T22:16:25.643","lastModified":"2026-06-17T10:46:29.013"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
