When parsing memcached storage commands, the parser accepts extremely large byte values without checking if adding the delimiter length will overflow, causing a negative value that triggers a runtime panic (a sudden crash caused by an error the program cannot recover from).","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-43g7-cwr8-q3jh","publishedAt":"2026-05-18T20:21:52.000Z","cveId":"CVE-2026-45686","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["go.opentelemetry.io/obi@>= 0.7.0, < 0.9.0 (fixed: 0.9.0)"],"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":"2026-05-18T20:21:52.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.75,"researchCategory":null,"atlasIds":null}}
