CVE-2025-31067

Vulnerability

Overview

The WordPress theme Seven Stars (versions n/a through 1.4.4) contains a stored cross-site scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation [1]. This flaw allows an authenticated user with sufficient privileges to inject malicious scripts that are stored on the server and later executed in the browsers of other users visiting the affected pages.

Exploitation

Conditions

Exploitation requires a privileged user role (e.g., Author or higher) to submit crafted input, such as a comment or post content, that is not properly sanitized by the theme [1]. No additional user interaction is needed for the initial injection, but a victim (e.g., site visitor or administrator) must subsequently view the page containing the stored payload to trigger execution.

Impact

A successful attack enables the attacker to execute arbitrary JavaScript in the context of the victim's browser. This can lead to session hijacking, redirection to malicious sites, defacement of the website, or theft of sensitive information such as cookies or login credentials [1]. The vulnerability is considered moderately dangerous and is anticipated to be used in mass-exploit campaigns targeting WordPress sites.

Mitigation

Status

The vendor has not yet released a patched version of the theme. As an immediate mitigation, users are advised to apply a virtual patch or web application firewall rule (e.g., provided by Patchstack) to block attacks until an official update is available and can be safely deployed [1].
