Executive Summary

CVE-2026-120325 is a path traversal vulnerability in Webpro-nl Knip up to version 6.44.0. The issue occurs in the writeFile function of IssueFixer.ts where manipulation of the workspaces argument allows attackers to access files outside the intended directory. This happens when a victim runs the knip --fix command with a malicious workspace path, causing the tool to scan and modify files beyond the repository.

Detection Guidance

Check if Knip versions 6.39.0 or earlier are installed by running: npm list -g knip or npm list knip. Inspect package.json and knip.json files for malicious workspace paths like ../victim-external. Monitor file system changes after running knip --fix for unexpected deletions or modifications.

Impact Analysis

This vulnerability can allow attackers to delete or overwrite sensitive files on your system by tricking you into running a malicious knip --fix command. It may lead to data loss, code injection into other projects, or compromise of confidential information stored outside the repository.

Compliance Impact

This vulnerability could lead to unauthorized file deletion or overwriting outside the repository, potentially exposing or destroying sensitive data. This may violate GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information if such data is affected.

Mitigation Strategies

Upgrade Knip to the latest version if available. Avoid running knip --fix on untrusted repositories. Implement path containment checks in workspace resolution and validate glob patterns to prevent escaping the repository root.
