A low-privileged local user could create that directory and place a malicious configuration file, which would load for any user launching Claude Code on the same machine. Exploitation requires a shared multi-user Windows system and a victim who launches Claude Code after the file is placed.","solution":"Users on standard Claude Code auto-update have already received the fix. Users performing manual updates are advised to update to the latest version.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-5cwg-9f6j-9jvx","publishedAt":"2026-04-17T22:19:38.000Z","cveId":"CVE-2026-35603","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":[],"issueType":"vulnerability","affectedPackages":["@anthropic-ai/claude-code@< 2.1.75 (fixed: 2.1.75)"],"affectedPackageNames":["@anthropic-ai/claude-code"],"affectedPackageRefs":["npm:@anthropic-ai/claude-code"],"affectedVendors":[],"affectedVendorsRaw":["Claude Code"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00151,"epssCheckedAt":"2026-10-14T06:09:07.922Z","kevDateAdded":null,"advisoryAliases":["GHSA-5cwg-9f6j-9jvx"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-04-17T22:19:38.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
