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":"2026-04-17T20:38:49.901+00:00","modifiedAt":"2026-04-20T14:57:47.669+00:00","affected":[{"ecosystem":"Vendor product","name":"claude-code","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"anthropics\",\n                    \"product\": \"claude-code\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.1.75\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-5cwg-9f6j-9jvx"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-35603","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-35603","identifiers":["CVE-2026-35603"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
