CVE-2026-28042

Vulnerability

Overview CVE-2026-28042 is a reflected cross-site scripting (XSS) vulnerability in the Astoundify Listify WordPress theme, affecting versions from n/a through 3.2.5. The root cause is improper neutralization of user-supplied input during web page generation, allowing an attacker to inject arbitrary HTML or JavaScript into a reflected response. [1]

Exploitation

Method To exploit this vulnerability, an attacker must craft a malicious link or form submission containing the payload. Successful exploitation requires user interaction—a privileged user (such as an administrator) must click the crafted link, visit a specially crafted page, or submit a manipulated form. The injected payload then executes within the context of the victim's browser session. [1]

Impact

If exploited, an attacker can inject malicious scripts that perform actions such as redirecting visitors to attacker-controlled sites, displaying unauthorized advertisements, or embedding other HTML payloads. This can compromise the integrity of the affected site and its visitors' experience. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns targeting thousands of WordPress installations. [1]

Mitigation

As of the publication date, an official patch for Listify was not yet available. The advisory recommends immediately updating the theme when a patched version is released. In the interim, a mitigation rule from Patchstack can block attacks until an official fix is applied. Users unable to update should consult their hosting provider for assistance. [1]
