An attacker can exploit this by preparing a malicious repository that, when opened by a user, tricks Codex into running file-writing commands without asking for permission, potentially modifying Codex's configuration to launch attacker-controlled code with the user's privileges.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-19591","publishedAt":"2026-09-01T18:17:40.260Z","cveId":"CVE-2026-19591","cweIds":["CWE-150"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI","Codex CLI","Codex Desktop"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-09-01T18:17:40.260Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":["AML.T0010"]}}
