{"id":"CVE-2025-13437","summary":"Arbitrary node_modules Directory Deletion in Google zx","details":"When zx is invoked with --prefer-local=\u003cpath\u003e, the CLI creates a symlink named ./node_modules pointing to \u003cpath\u003e/node_modules. Due to a logic error in src/cli.ts (linkNodeModules / cleanup), the function returns the target path instead of the alias (symlink path). The later cleanup routine removes what it received, which deletes the target directory itself. Result: zx can delete an external \u003cpath\u003e/node_modules outside the current working directory.","aliases":["GHSA-w87r-vg9q-crqm"],"modified":"2026-08-12T03:51:47.692192770Z","published":"2025-11-20T16:25:16.866Z","database_specific":{"cwe_ids":["CWE-706"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/13xxx/CVE-2025-13437.json","cna_assigner":"Google"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/13xxx/CVE-2025-13437.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-13437"},{"type":"REPORT","url":"https://github.com/google/zx/issues/1348"},{"type":"PACKAGE","url":"https://github.com/google/zx"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/google/zx","events":[{"introduced":"bfa8e6a2653d498991d95f8913779ad1ad1fa827"},{"last_affected":"bfa8e6a2653d498991d95f8913779ad1ad1fa827"}],"database_specific":{"extracted_events":[{"introduced":"8.8.4"},{"last_affected":"8.8.4"}],"source":"AFFECTED_FIELD"}}],"versions":["8.8.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-13437.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H/E:U"}]}
