The model was able to find complex vulnerabilities, including some that traditional automated testing tools (called fuzzers, which automatically test software with random inputs) struggle to detect, and all discovered flaws were validated and have since been patched by the software maintainers.","solution":"The CGIF heap buffer overflow vulnerability was fixed in version 0.5.1. The source text notes that Anthropic emphasized the importance of 'promptly patching known vulnerabilities,' but does not describe mitigation steps for the other vulnerabilities beyond noting they have been patched by their respective maintainers.","labels":["security","research"],"sourceUrl":"https://thehackernews.com/2026/02/claude-opus-46-finds-500-high-severity.html","publishedAt":"2026-02-06T05:49:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Claude Opus 4.6","Ghostscript","OpenSC","CGIF"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
