| Title | Z-Blog Z-BlogPHP 1.7.5 Upload any file |
|---|
| Description | Z-BlogPHP `App::UnPack()` method parses application packages (ZBA files) by decoding base64-encoded file content and writing it directly to the filesystem without any security verification. Attackers can craft malicious ZBA files to upload files containing malicious code, thereby achieving remote code execution. |
