AI-suggested
Upgrade to @wakaru/cli version 1.4.0 or later, where this path traversal vulnerability is fixed. No other mitigation or temporary workaround is documented. Patch status is not explicitly stated but the fix is included in version 1.4.0, so updating to this version or newer is recommended.
Description
wakaru is a JavaScript decompiler and unminifier toolkit. From 1.0.0 until 1.4.0, @wakaru/cli sanitizes bundle-controlled module filenames only once before writing extracted modules, so a crafted filename containing overlapping traversal sequences such as ....// collapses to ../ after sanitization and lets the final output path escape the selected output directory, allowing an attacker who can cause a user to run wakaru --unpack on a malicious bundle to write files outside that directory and, depending on the target path and environment, potentially achieve code execution. This issue is fixed in @wakaru/cli 1.4.0.
