Its CoworkVMService component runs as SYSTEM and does not check whether the VM bundle directory is a real directory or an NTFS directory junction before creating files in it. A local non-elevated user can replace that user-writable directory with a junction pointing to an attacker-chosen location, causing the service to create a SYSTEM-owned file in an arbitrary directory, which can be used for local privilege escalation.","solution":"Fixed in 1.3834.0.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44470","publishedAt":"2026-05-13T16:16:58.263Z","cveId":"CVE-2026-44470","cweIds":["CWE-59","CWE-269"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":[],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Claude Desktop","Claude Code"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Claude Desktop for Windows local privilege escalation via directory junction","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00159,"epssCheckedAt":"2026-10-14T18:05:58.741Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-10-10T03:48:23.738Z","patchAvailable":null,"disclosureDate":"2026-05-13T16:16:58.263Z","capecIds":["CAPEC-122"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.8,"researchCategory":null,"atlasIds":null}}
