Summary
The template upload feature in Emlog Pro v2.6.9 has a path traversal vulnerability, allowing authenticated administrators to execute arbitrary PHP code. By uploading a malicious ZIP archive containing directory traversal sequences in filenames, an attacker can overwrite default template files or directly include malicious code files in the current template.
Risk Assessment
The risk involves potential server compromise through arbitrary PHP code execution, which could lead to data theft, content modification, or further attacks on the infrastructure.
Recommendation
Immediately update Emlog Pro to the latest version that fixes this vulnerability, and restrict administrator privileges to the minimum necessary for their work.
Other vulnerabilities in Emlog Pro
See all- CVE-2025-61318Critical
Emlog Pro 2.5.20 has an arbitrary file deletion vulnerability. It stems from the admin/template.php and admin/plugin.php components, which fail to perform path verification and dangerous code filtering for deletion parameters, allowing attackers to exploit this feature for directory traversal.
- CVE-2025-25783Critical

- CVE-2026-67598High
Emlog Pro through 2.6.23 contains a disabled TLS certificate validation vulnerability in include/service/ai.php that allows network-adjacent attackers to intercept outbound HTTPS requests to configured LLM providers by presenting arbitrary TLS certificates, as CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST are unconditionally disabled across sendStream(), sendImageRequest(), send(), and fetchSearchHtml() with no option to re-enable verification.
- CVE-2025-44139High
Emlog Pro V2.5.7 is vulnerable to unrestricted file upload of dangerous types via the /emlog/admin/plugin.php?action=upload_zip endpoint. An attacker can upload a malicious ZIP file that gets extracted and executed on the server.
