This can crash the application or give attackers unauthorized access to system files.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-8qvf-mr4w-9x2c","publishedAt":"2026-03-18T20:01:21.000Z","cveId":"CVE-2026-33054","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["mesop@<= 1.2.2 (fixed: 1.2.3)"],"affectedVendors":["Google"],"affectedVendorsRaw":["Google Mesop"],"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":"2026-03-18T20:01:21.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":["AML.T0010"]}}
