CVE-2026-54545

HIGH
7.1
CVSS 3.1
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.
