## What is CVE-2026-25724?

CVE-2026-25724 is a low-severity vulnerability in anthropics claude-code, published on 6 Feb 2026. 

### Official 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.

Weakness: CWE-61 (UNIX Symbolic Link (Symlink) Following), CWE-285 (Improper Authorization)

Check this codebase for CVE-2026-25724 and fix it if it is affected.

What it is: CVE-2026-25724 is a low-severity vulnerability in anthropics claude-code, published on 6 Feb 2026. 
Exploitation: There is no known exploitation of CVE-2026-25724 in the wild and no public exploit code.

Affected packages and fixed versions:
- @anthropic-ai/claude-code (npm): affected all versions; fixed in 2.1.7
- @anthropic-ai/claude-code (npm): affected all versions; fixed in 2.1.7

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
