What is CVE-2026-34607?

Emlog, an open-source website building system, is susceptible to a path traversal vulnerability in the emUnZip() function. This issue affects versions 2.6.2 and earlier. When an authenticated admin uploads a specially crafted ZIP archive with malicious entry names that leverage ../ sequences, the system's extractTo() function fails to properly sanitize these entries. This oversight allows attackers to write arbitrary files on the server, including malicious PHP webshells, leading to potential remote code execution. Currently, there are no available patches to mitigate this vulnerability.
