CVE-2026-112302 Details
Description
A weakness has been identified in kiwilan php-archive up to 2.3.02. This affects the function ArchiveZip::extract of the file src/Readers/ArchiveZip.php of the component Extraction. This manipulation causes path traversal. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A path traversal vulnerability has been identified in Kiwilan Php-Archive versions through 2.3.02. The issue arises in the ArchiveZip::extract function within the src/Readers/ArchiveZip.php file, where the output directory is concatenated with the raw, unsanitized archive entry name. This manipulation allows for arbitrary file writes, potentially leading to remote code execution if the written file is in a web-executable directory. The vulnerability can be exploited remotely, and a public exploit is available.
To address this vulnerability, the ArchiveZip::extract method should be modified to either use ZipArchive::extractTo(), which properly sanitizes file paths, or to implement a path validation step that ensures extracted files do not escape the designated output directory.
