Prior to version 2.0.65, vulnerability in Claude Code's project-load flow…","summary":"Prior to version 2.0.65, Claude Code's project-load flow let a malicious repository exfiltrate data, including Anthropic API keys, before the user confirmed trust. A repository settings file could set ANTHROPIC_BASE_URL to an attacker-controlled endpoint, and Claude Code issued API requests on opening the repository, before the trust prompt appeared.","solution":"Fixed in 2.0.65, which contains a patch. Users on standard auto-update have already received the fix; users performing manual updates should update to version 2.0.65 or the latest version.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-21852","publishedAt":"2026-01-22T02:16:08.693Z","cveId":"CVE-2026-21852","cweIds":["CWE-522"],"cvssScore":"7.5","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["@anthropic-ai/claude-code@< 2.0.65 (fixed: 2.0.65)"],"affectedPackageNames":["@anthropic-ai/claude-code"],"affectedPackageRefs":["npm:@anthropic-ai/claude-code"],"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Claude Code"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Claude Code project-load flow leaks API keys before trust prompt","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.27504,"epssCheckedAt":"2026-11-04T06:10:15.563Z","kevDateAdded":null,"advisoryAliases":["GHSA-jh7p-qr78-84p7"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:51:17.203Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2025-12-11T02:41:29.924Z","daysToFix":-42,"fixCheckedAt":"2026-10-29T21:42:03.675Z","capecIds":null,"crossRefCount":1,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","fixedVersion":"2.0.65","matchedVersion":"2.0.65","fixReleasedAt":"2025-12-11T02:41:29.924Z","daysToFix":-42,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:42:03.524Z"}]}}
