In one case, GPT-5.5-Cyber independently built sophisticated fuzzing tools (automated testing systems that find bugs by trying many unexpected inputs) for zlib, a widely-used compression library, discovering new vulnerabilities in just one day without being explicitly instructed how to do so.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://blog.trailofbits.com/2026/07/02/field-reports-from-patch-the-planet/","publishedAt":"2026-07-02T11:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI","GPT-5.5-Cyber","zlib"],"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":"2026-07-02T11:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
