Both vulnerabilities stem from a shared problem: the \"harness\" (the code that sits between the AI model and actual system execution) marked certain values as safe but then used them with higher privileges, letting attackers bypass security checks.","solution":"Update Gemini CLI to 0.39.1, run-gemini-cli to 0.1.22, and Claude Code to 2.1.163, then audit any workflow that outside users can trigger. For OpenAI's Codex, separate the two Codex passes into different jobs, run Codex with drop-sudo (restricted privileges) and a read-only sandbox, and run Codex as the last step in a job rather than before privileged steps that could use files it leaves behind.","labels":["security"],"sourceUrl":"https://thehackernews.com/2026/08/claude-code-and-gemini-cli-flaws-let.html","publishedAt":"2026-08-07T08:18:35.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["prompt_injection","supply_chain"],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic","Google","OpenAI"],"affectedVendorsRaw":["Anthropic","Claude Code","Google","Gemini CLI","OpenAI","Codex","Hugging Face"],"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":"2026-08-07T08:18:35.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
