WordPress Spark Multipurpose theme <= 1.0.7 - Cross Site Scripting (XSS) Vulnerability

Published Jun 20, 2025 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed

Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in sparklewpthemes Spark Multipurpose spark-multipurpose allows DOM-Based XSS.This issue affects Spark Multipurpose: from n/a through <= 1.0.7.

Analysis

Technical impact

This vulnerability is caused by improper neutralization of user input during web page generation, resulting in a DOM‑based cross‑site scripting flaw. An attacker can inject malicious scripts into the theme’s front‑end pages, which are then executed in the browsers of unsuspecting visitors. The attack could allow defacement, credential theft, or delivery of further malware by hijacking user sessions.

Affected Systems

The flaw is present in the WordPress theme Spark Multipurpose, version 1.0.7 and older, developed by sparklewpthemes. All installations of the theme at or below 1.0.7 are affected; newer releases are not mentioned as vulnerable.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity, while the EPSS score of <1% suggests a low likelihood of current exploitation. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires a user to view a web page that includes the vulnerable output, so the attack surface is limited to the theme's front‑end. Immediate patching is the most effective mitigation.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Add a Content Security Policy header to reduce the impact of any retained scripts.
