CVE-2026-25724

Q: How do I fix CVE-2026-25724?

Upgrade claude code to 2.1.7 or later.

Q: Is CVE-2026-25724 being actively exploited?

Not that we know of. CVE-2026-25724 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.38% is the estimated probability that it will be exploited in the next 30 days. That is higher than 30% of all scored CVEs.

Q: How severe is CVE-2026-25724?

CVE-2026-25724 has a CVSS v3 base score of 7.5, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

Q: What does CVE-2026-25724 affect?

Published advisories record a fix for claude code (NVD). Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.

Description

Claude Code is an agentic coding tool. 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.
