This vulnerability (CVE-2026-27385) affects designthemes DesignThemes Portfolio (<= 1.3) and is caused by improper neutralization of input during web page generation, resulting in a reflected cross-site scripting (XSS) flaw. The CVSS 3.1 base score is 7.1 (high), with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability. The vulnerability allows an attacker to inject malicious scripts that execute in the victim's browser when they visit a crafted URL or page, potentially leading to session hijacking or other malicious actions. No patch or official remediation guidance is currently provided.

Successful exploitation of this reflected XSS vulnerability can lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data. Attackers can execute arbitrary scripts in the context of the victim's browser, which may result in theft of sensitive information, session hijacking, or other malicious activities. However, no known exploits in the wild have been reported so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when interacting with untrusted links or inputs in affected versions of DesignThemes Portfolio. Implementing web application firewalls (WAFs) with XSS filtering may provide temporary mitigation.
