Its agents start a development server for a pull request, resize the browser to an iPhone-sized viewport, and simulate user workflows to catch problems such as a button that disappears. The company also says it indexes customer codebases and serves that documentation to Codex through an MCP server, and tracks AI-generated code reverts as a measure of impact.","solution":"N/A -- no mitigation discussed in source.","labels":["industry"],"sourceUrl":"https://openai.com/index/greptile-code-review-codex-astra","publishedAt":"2026-10-26T22:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["GPT-6 Astra","Daybreak","Codex","Greptile"],"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":"2026-10-26T22:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
