Prior to version 2.1.7, Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file (such as /etc/passwd) and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude Code to read the restricted file through the symlink without triggering deny rule enforcement. This issue has been patched in version 2.1.7.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:L/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:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-61","CWE-285"],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-4q92-rfm6-2cqx","https://www.terra.security/blog/when-ai-becomes-the-attack-surface-lessons-from-discovering-cve-2026-25724"],"products":["anthropic:claude_code"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-25724","score":0.00465,"percentile":0.40265,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4q92-rfm6-2cqx","url":"https://osv.dev/vulnerability/GHSA-4q92-rfm6-2cqx","summary":"Claude Code has Permission Deny Bypass Through Symbolic Links","modified":"2026-04-12T05:17:45.956376Z","packages":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","purl":"pkg:npm/%40anthropic-ai/claude-code","ranges":["<2.1.7"],"fixed":["2.1.7"]}]}],"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).
