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":"2026-08-24T22:16:53.02+00:00","modifiedAt":"2026-10-12T15:10:00.207+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/open-telemetry/opentelemetry-go/commit/93a693edeed0e07ce5ebd1dfe67af42d1e2055d8","https://github.com/open-telemetry/opentelemetry-go/pull/8693","https://github.com/open-telemetry/opentelemetry-go/releases/tag/v1.45.0","https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-42cj-99w8-cp2p"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-45404","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-362","CWE-667"],"productCriteria":[],"sourceDates":{"published":"2026-08-24T22:16:53.020","lastModified":"2026-10-12T15:10:00.207"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
