If a user opens an attacker-prepared repository and Codex follows its instructions, Codex can run a file-writing Git command without requesting approval. If filesystem protections permit the write, the attacker can modify Codex's configuration so that a later load launches an attacker-controlled MCP server, executing 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":["prompt_injection","other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI Codex CLI","Codex Desktop","Codex"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"OpenAI Codex CLI and Desktop approval bypass via PowerShell","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00559,"epssCheckedAt":"2026-11-04T18:09:14.312Z","kevDateAdded":null,"advisoryAliases":["GHSA-2frj-4qr5-m2rf"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-01T18:08:50.148Z","patchAvailable":null,"disclosureDate":"2026-09-01T18:17:40.260Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality","availability"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":["AML.T0051"],"fixes":[]}}
