CVE-2025-0450: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in MuffinGroup Betheme
The Betheme plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's custom JS functionality in all versions up to, and including, 27.6.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-0450 is a stored cross-site scripting vulnerability in the MuffinGroup Betheme WordPress plugin, present in all versions up to 27.6.1. It allows authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript via the plugin's custom JS feature due to improper input sanitization and output escaping. This script executes whenever a user accesses the affected page, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 score of 6.4, reflecting medium severity with network attack vector and low complexity. No patch or official fix information is currently available in the provided data.
Potential Impact
An attacker with contributor-level or higher privileges can inject persistent malicious scripts into pages generated by the Betheme plugin. These scripts execute in the context of users viewing the infected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not affect availability and requires authenticated access, limiting the attack surface to users with some level of trust on the site.
Mitigation Recommendations
Patch status is not yet confirmed—check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting the use of the plugin's custom JavaScript functionality to reduce risk.
