Vulnerability Details

The vulnerability described in CVE-2026-32390 is due to Missing Authorization in linethemes Nanosoft, which enables exploitation through incorrectly configured access control security levels. The CVSS score of 5.4 indicates a medium severity level, reflecting a moderate risk that organizations face. This vulnerability specifically affects Nanosoft versions from n/a through less than 1.3.2. Published on March 13, 2026, it is classified under CWE-862.

Technical Analysis

The root cause of CVE-2026-32390 lies in the lack of proper authorization checks within the Nanosoft theme, leading to potentially unauthorized actions by users with low privileges. The attack vector is network-based, and the complexity level is low, requiring minimal effort to exploit.

The attack does not require user interaction, making it easier for attackers to execute. The vulnerability affects the integrity and availability of the system, as unauthorized actions could modify or disrupt service functionality. However, it does not impact confidentiality, meaning sensitive data remains protected if other security measures are in place.

Risk & Impact Analysis

The real-world deployment risk associated with CVE-2026-32390 is significant. Organizations using the Nanosoft theme should recognize the potential for unauthorized access that could compromise the integrity of the system. The blast radius could extend to any user with low privileges, leading to the possibility of unauthorized data manipulation or service disruption.

Given the CVSS score of 5.4, organizations should prioritize addressing this vulnerability in their patch cycle, ensuring that affected systems are remediated promptly to prevent exploitation.

Exploitation Status

Affected Versions
