What is CVE-2026-92205?

The BusyBox libarchive component contains a vulnerability that allows remote attackers to exploit symlink directory traversal, leading to arbitrary file creation on affected systems. This flaw emerges due to insufficient validation of user-supplied paths before executing file operations. For successful exploitation, user interaction is necessary, as the target must access a specially crafted web page or file. This could lead to unauthorized file modifications within the context of the current user, raising significant security concerns.
