CVE-2026-34228 WRITEUP MEDIUM WRITEUP
Emlog: CSRF in Backend Upgrade Interface Leading to Arbitrary Remote SQL Execution and Arbitrary File Write
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.

CVE-2025-47784 WRITEUP CRITICAL WRITEUP
emlog < 2.5.14 - Deserialization of Untrusted Data via Crafted Nickname
Emlog is an open source website building system. Versions 2.5.13 and prior have a deserialization vulnerability. A user who creates a carefully crafted nickname can cause `str_replace` to replace the value of `name_orig` with empty, causing deserialization to fail and return `false`. Commit 9643250802188b791419e3c2188577073256a8a2 fixes the issue.
CVSS 9.8
CVE-2025-47787 WRITEUP CRITICAL WRITEUP
emlog < 2.5.10 - Remote Code Execution via Insufficient ZIP Plugin Validation
Emlog is an open source website building system. Emlog Pro prior to version 2.5.10 contains a file upload vulnerability. The store.php component contains a critical security flaw where it fails to properly validate the contents of remotely downloaded ZIP plugin files. This insufficient validation allows attackers to execute arbitrary code on the vulnerable system. Version 2.5.10 contains a patch for the issue.
CVSS 9.8
CVE-2025-61769 WRITEUP MEDIUM WRITEUP
emlog <= 2.5.22 - Authenticated Stored Cross-Site Scripting via SVG File Upload
Emlog is an open source website building system. A cross-site scripting (XSS) vulnerability in emlog up to and including version 2.5.22 allows authenticated remote attackers to inject arbitrary web script or HTML via the file upload functionality. As an authenticated user it is possible to upload .svg file that contains JavaScript code that is later being executed. Commit 052f9c4226b2c0014bcd857fec47677340b185b1 fixes the issue.
CVSS 6.1
CVE-2025-62717 WRITEUP CRITICAL WRITEUP
emlog 2.5.23 - Improper Authentication via Session Verification Code Reuse
Emlog is an open source website building system. In version 2.5.23, Emlog Pro is vulnerable to a session verification code error due to a clearing logic error. This means the verification code could be reused anywhere an email verification code is required. This issue has been fixed in commit 1f726df.
CVSS 9.1
CVE-2026-22799 WRITEUP HIGH WRITEUP
emlog < 2.6.1 - Authenticated Arbitrary File Upload via REST API Endpoint
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.
