If a user explicitly denied Claude Code access to a file and Claude Code had access to a symlink pointing to that file, it was possible for Claude Code to access the file. \n\nUsers on standard Claude Code auto-update will have received this fix automatically. Users performing manual updates are advised to update to the latest version.\n\nThank you to https://hackerone.com/vinai for reporting this issue!","state":0,"publishedAt":"2025-10-03T14:17:58+00:00","modifiedAt":"2025-10-13T15:10:14+00:00","affected":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.0.120"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-66m2-gx93-v996","https://nvd.nist.gov/vuln/detail/CVE-2025-59829","https://github.com/anthropics/claude-code"],"sourceUrl":"https://github.com/advisories/GHSA-66m2-gx93-v996","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-66m2-gx93-v996","identifiers":["GHSA-66m2-gx93-v996","CVE-2025-59829"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
