Emlog is an open source website building system. In versions 2.6.2 and prior, a SQL injection vulnerability exists in include/model/tag_model.php at line 168. The updateTagName() function directly interpolates user input into the SQL query string without using parameterized queries or proper escaping ($this->db->escape_string()), making it vulnerable to SQL injection attacks. At time of publication, there are no publicly available patches.

Emlog is an open source website building system. Prior to version 2.6.8, the backend upgrade interface accepts remote SQL and ZIP URLs via GET parameters. The server first downloads and executes the SQL file, then downloads the ZIP file and extracts it directly into the web root directory. This process does not validate a CSRF token. Therefore, an attacker only needs to trick an authenticated administrator into visiting a malicious link to achieve arbitrary SQL execution and arbitrary file write. This issue has been patched in version 2.6.8.

Emlog is an open source website building system. In versions 2.6.2 and prior, a path traversal vulnerability exists in the emUnZip() function (include/lib/common.php:793). When extracting ZIP archives (plugin/template uploads, backup imports), the function calls $zip->extractTo($path) without sanitizing ZIP entry names. An authenticated admin can upload a crafted ZIP containing entries with ../ sequences to write arbitrary files to the server filesystem, including PHP webshells, achieving Remote Code Execution (RCE). At time of publication, there are no publicly available patches.

Emlog is an open source website building system. In versions 2.6.2 and prior, a Local File Inclusion (LFI) vulnerability exists in admin/plugin.php at line 80. The $plugin parameter from the GET request is directly used in a require_once path without proper sanitization. If the CSRF token check can be bypassed (see potential bypass conditions), an attacker can include arbitrary PHP files from the server filesystem, leading to code execution. At time of publication, there are no publicly available patches.

Emlog is an open source website building system. emlog v2.6.1 and earlier exposes a REST API endpoint (/index.php?rest-api=upload) for media file uploads. The endpoint fails to implement proper validation of file types, extensions, and content, allowing authenticated attackers (with a valid API key or admin session cookie) to upload arbitrary files (including malicious PHP scripts) to the server. An attacker can obtain the API key either by gaining administrator access to enable the REST API setting, or via information disclosure vulnerabilities in the application. Once uploaded, the malicious PHP file can be executed to gain remote code execution (RCE) on the target server, leading to full server compromise.
