They reached OpenAI's GitHub repository called \"Monorepo\" and sent a pull request from an employee's Codex account as proof, but did not access its internal code. The source says they got in through Discourse, a third-party service hosting OpenAI's community forum.","solution":"N/A -- no mitigation discussed in source.","labels":["security","industry"],"sourceUrl":"https://www.theverge.com/ai-artificial-intelligence/997444/openai-hack-claude-heif-heist","publishedAt":"2026-09-18T15:30:16.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"medium","attackType":["other"],"issueType":"news","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["OpenAI","Anthropic"],"affectedVendorsRaw":["OpenAI","Anthropic","Claude Opus","Codex","GitHub","Discourse"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-09-18T15:30:16.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.8,"researchCategory":null,"atlasIds":null}}
