When one goroutine (lightweight thread) writes baggage items while another reads them simultaneously, Go crashes the process with a fatal error. This is low severity because it requires specific configuration of the OpenTracing bridge and concurrent access to the same span.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-42cj-99w8-cp2p","publishedAt":"2026-08-20T17:26:14.000Z","cveId":"CVE-2026-45404","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["go.opentelemetry.io/otel/bridge/opentracing@>= 0.11.0, < 1.45.0 (fixed: 1.45.0)"],"affectedVendors":[],"affectedVendorsRaw":["OpenTelemetry"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-08-20T17:26:14.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.75,"researchCategory":null,"atlasIds":null}}
