## What is CVE-2025-59041?

CVE-2025-59041 is a high-severity code injection vulnerability in anthropics claude-code, published on 10 Sep 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Claude Code is an agentic coding tool. At startup, Claude Code executed a command templated in with `git config user.email`. Prior to version 1.0.105, a maliciously configured user email in git could be used to trigger arbitrary code execution before a user accepted the workspace trust dialog. Users on standard Claude Code auto-update will have received this fix automatically. Users performing manual updates are advised to update to version 1.0.105 or the latest version.

Weakness: CWE-94 (Improper Control of Generation of Code)

Check this codebase for CVE-2025-59041 and fix it if it is affected.

What it is: CVE-2025-59041 is a high-severity code injection vulnerability in anthropics claude-code, published on 10 Sep 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-59041 exists.

Affected packages and fixed versions:
- @anthropic-ai/claude-code (npm): affected all versions; fixed in 1.0.105
- @anthropic-ai/claude-code (npm): affected all versions; fixed in 1.0.105

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.
