This could make the application slower or crash.","solution":"Introduce a bounded, thread-safe LRU cache (a cache that automatically removes the least recently used items when full) for remote endpoints and enforce a fixed maximum size to prevent unbounded growth. See PR #7081 in the opentelemetry-dotnet repository for the fix.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-88hf-wf7h-7w4m","publishedAt":"2026-04-28T23:23:28.000Z","cveId":"CVE-2026-41310","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["OpenTelemetry.Exporter.Zipkin@<= 1.15.2 (fixed: 1.15.3)"],"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":"2026-04-28T23:23:28.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.72,"researchCategory":null,"atlasIds":null}}
