In versions prior to 2.1.75 on Windows, Claude Code loaded the system-wide default configuration from C:\\ProgramData\\ClaudeCode\\managed-settings.json without validating directory ownership or access permissions. Because the ProgramData directory is writable by non-administrative users by default and the ClaudeCode subdirectory was not pre-created or access-restricted, a low-privileged local user could create this directory and place a malicious configuration file that would be automatically loaded for any user launching Claude Code on the same machine. Exploiting this would have required a shared multi-user Windows system and a victim user to launch Claude Code after the malicious configuration was placed. This issue has been fixed on version 2.1.75.","state":0,"publishedAt":"2026-04-17T21:16:33.507+00:00","modifiedAt":"2026-06-17T10:40:50.897+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":5.4,"severity":"MEDIUM"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":7.3,"severity":"HIGH"}],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-5cwg-9f6j-9jvx"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35603","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-426"],"productCriteria":["cpe:2.3:a:anthropic:claude_code:*:*:*:*:*:node.js:*:*","cpe:2.3:o:microsoft:windows:-:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-04-17T21:16:33.507","lastModified":"2026-06-17T10:40:50.897"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
