A recently disclosed ZipSlip vulnerability in kkFileView, a popular file preview tool, allows attackers to achieve remote code execution by exploiting path traversal during archive extraction. The flaw, triggered by a single malicious archive, can lead to full server compromise. This vulnerability is particularly dangerous because kkFileView is widely used in enterprise environments for document previews. Security teams should immediately apply patches or implement mitigations such as input validation and sandboxing. The signal underscores the ongoing risks associated with file upload and extraction functionalities, which are common in many applications.
