Versions below 1.0.120 failed to account for symlinks when checking permission deny rules. 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. Users on standard Claude Code auto-update will have received this fix automatically. Users performing manual updates are advised to update to the latest version. This issue is fixed in version 1.0.120.","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":2.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-61"],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-66m2-gx93-v996"],"products":["anthropic:claude_code"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-59829","score":0.00447,"percentile":0.38636,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-66m2-gx93-v996","url":"https://osv.dev/vulnerability/GHSA-66m2-gx93-v996","summary":"Claude Code permission deny bypass through symlink","modified":"2025-10-13T15:10:14Z","packages":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","purl":"pkg:npm/%40anthropic-ai/claude-code","ranges":["<1.0.120"],"fixed":["1.0.120"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
