Users performing manual updates are advised to update to the latest version.\n\nThank you to https://hackerone.com/vinai for reporting this issue!","published":"2025-10-03T14:17:58Z","modified":"2025-10-13T15:10:14Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","fixedVersion":"1.0.120"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/anthropics/claude-code/security/advisories/GHSA-66m2-gx93-v996"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59829"},{"type":"PACKAGE","url":"https://github.com/anthropics/claude-code"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2025-10-13T15:10:14Z"}}
