Executive Summary

CVE-2026-39899 is a vulnerability in Cacti, an open source performance and fault management framework. Versions 1.2.30 and earlier are affected by a Path Traversal vulnerability through the filename parameter in the package_import.php file. This means an attacker could manipulate the filename parameter to access files outside the intended directory.

This issue was fixed in version 1.2.31.

Impact Analysis

The Path Traversal vulnerability allows an attacker to potentially read arbitrary files on the server where Cacti is installed. This could lead to unauthorized access to sensitive information, configuration files, or other data that should be protected.

Since the vulnerability can be exploited remotely without authentication (as indicated by the CVSS vector AV:N/AC:L/PR:N/UI:N), it poses a significant security risk.

Mitigation Strategies

The vulnerability in Cacti versions 1.2.30 and prior can be mitigated by upgrading to version 1.2.31 or later, where the issue has been fixed.
