From version 0.11.0 through 1.44.0, the OpenTracing bridge's bridgeSpan contains an unsynchronized extraBaggageItems map which can cause a panic. Because Go maps are not safe for concurrent read/write access, concurrent SetBaggageItem and correlation.MapFromContext calls on the same hooked bridgeSpan can trigger a fatal runtime error—such as concurrent map read and map write or concurrent map iteration and map write—terminating the process and causing denial of service. This issue is fixed in version 1.45.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":5.9,"severity":null}],"references":["https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-42cj-99w8-cp2p","https://github.com/open-telemetry/opentelemetry-go/pull/8693","https://github.com/open-telemetry/opentelemetry-go/commit/93a693edeed0e07ce5ebd1dfe67af42d1e2055d8","https://github.com/open-telemetry/opentelemetry-go/releases/tag/v1.45.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-65155","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 24, 2026, 9:19:00 PM","dateUpdated":"Aug 27, 2026, 2:18:58 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
