CVE-2026-112049 [MEDIUM] – Vita3K before build 4187 contains a path traversal (zip slip) vulnerability in install_arc

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.
