CVE-2026-112049 Details
Description
Vita3K before build 4187 contains a path traversal (zip slip) vulnerability in install_archive_content() that allows attackers to write files outside the install directory via crafted .vpk archives. Attackers can embed '..' segments or absolute paths in zip entry names to write attacker-controlled files anywhere writable by Vita3K, potentially enabling host code execution.
A path traversal vulnerability, also known as zip slip, has been identified in Vita3K versions prior to build 4187. The issue arises in the 'install_archive_content()' function, where the application extracts .vpk archive contents without properly validating the filenames. This flaw allows attackers to craft .vpk files that, when installed, can write files to locations outside the designated install directory, potentially leading to execution of host code.
Users can update to Vita3K build 4187 or later, where this vulnerability has been addressed.
