A malicious or corrupted executable can cause OBI to crash when it tries to analyze what programming language a process uses, disrupting monitoring for other applications on the system.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-wp73-mwgf-4jq9","publishedAt":"2026-05-18T17:56:06.000Z","cveId":"CVE-2026-45676","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["go.opentelemetry.io/obi@< 0.9.0 (fixed: 0.9.0)"],"affectedVendors":[],"affectedVendorsRaw":["OpenTelemetry","OpenTelemetry eBPF Instrumentation"],"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":"2026-05-18T17:56:06.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.75,"researchCategory":null,"atlasIds":null}}
