{"id":"CVE-2025-13437","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":"2026-04-10T05:21:13.914406Z","published":"2025-11-20T17:15:49.453Z","references":[{"type":"REPORT","url":"https://github.com/google/zx/issues/1348"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-13437.json"}}],"schema_version":"1.7.5","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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
