CVE-2026-27385

Vulnerability

Overview The DesignThemes Portfolio plugin for WordPress versions up to and including 1.3 suffers from a reflected cross-site scripting (XSS) vulnerability. The root cause is improper neutralization of user-supplied input during web page generation, allowing an attacker to inject arbitrary HTML and JavaScript into a response [1].

Exploitation

Details This reflected XSS requires user interaction—a victim must click a crafted link, visit a specially prepared page, or submit a malicious form. The attack does not require authentication for the initial injection, but successful exploitation depends on a privileged user (e.g., an administrator) performing the action [1]. Attackers can leverage this to target thousands of websites in mass-exploit campaigns, regardless of site traffic or popularity.

Impact

If exploited, an attacker can execute arbitrary scripts in the context of the victim's browser session. This can lead to redirects to malicious sites, injection of advertisements, theft of session cookies, or other actions that compromise the integrity of the website and its visitors [1].

Mitigation

The vulnerability is patched in version 1.5 of the plugin. Users are strongly advised to update immediately. For those unable to update, Patchstack provides a mitigation rule to block attacks until the update is applied. Hosting providers or web developers can assist with temporary workarounds [1].
