+  "summary": "@wakaru/cli arbitrary file write during bundle unpack",
+  "details": "### Impact\n\n`@wakaru/cli` is vulnerable to arbitrary file write when unpacking a crafted JavaScript bundle with `--unpack`.\n\nBundle-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.\n\nAn 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.\n\nAffected versions: `>=1.0.0 <1.4.0`.\n\n### Patches\n\nThe issue has been patched in `@wakaru/cli@1.4.0`.\n\nUsers should upgrade to:\n\n```sh\nnpm install @wakaru/cli@latest\n```\n\nor specifically:\n```\nnpm install @wakaru/cli@1.4.0\n```\n\n### Workarounds\n\nDo not run `wakaru --unpack` on untrusted or unknown bundles with affected versions.\n\nIf upgrading immediately is not possible, avoid using `--unpack on files that may be attacker-controlled.",
