@wakaru/cli is vulnerable to arbitrary file write when unpacking a crafted JavaScript bundle with --unpack.
Bundle-controlled module filenames were sanitized before writing extracted modules to the output directory. A crafted filename containing overlapping path traversal characters, such as ....//, could be transformed into ../ after sanitization. This allowed the final output path to escape the intended output directory.
An attacker who can cause a user to run wakaru --unpack on a malicious bundle may be able to write files outside the selected output directory. Depending on the target path and user environment, this may lead to code execution.
Affected versions: >=1.0.0 <1.4.0.
The issue has been patched in @wakaru/[email protected].
Users should upgrade to:
npm install @wakaru/cli@latest
or specifically:
npm install @wakaru/[email protected]
Do not run wakaru --unpack on untrusted or unknown bundles with affected versions.
If upgrading immediately is not possible, avoid using `--unpack on files that may be attacker-controlled.
@wakaru/cli >= 1.0.0, < 1.4.0Upgrade to a patched release:
@wakaru/cli 1.4.0Connected by shared product, vendor, weakness, or advisory.
