CVE-2026-94415 is a reflected Cross-site Scripting (XSS) vulnerability in Muffingroup Betheme that affects versions up to and including 28.5.8. This vulnerability arises from improper neutralization of input during web page generation, allowing an attacker to inject malicious scripts. The vulnerability has a high severity with a CVSS score of 7.1. No patch or remediation information is currently provided.

Betheme, a WordPress theme by MuffinGroup, contains a stored cross-site scripting (XSS) vulnerability in the 'icon_box_2' shortcode. This flaw affects all versions up to and including 28.4 and allows authenticated users with contributor-level access or higher to inject malicious scripts. These scripts execute when any user views the compromised page. The vulnerability arises from insufficient input sanitization and output escaping of user-supplied attributes.

CVE-2026-65548 is a critical remote code execution vulnerability in Muffingroup Betheme versions up to and including 28.4.2. It involves improper control of code generation (CWE-94), allowing a contributor-level user to execute arbitrary code remotely without user interaction. The vulnerability has a very high CVSS score of 9.9, indicating severe impact on confidentiality, integrity, and availability.

The Betheme theme for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 28.4. This is due to the upload_icons() function workflow moving and unzipping user-controlled ZIP files into a public uploads directory without validating extracted file types. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files (including PHP) and achieve remote code execution via the Icons icon-pack upload flow.

The Betheme theme for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 28.4. This is due to the upload_icons() function workflow using a user-controlled upload path (`mfn-icon-upload`) in a filesystem move operation without constraining it to the uploads directory. This makes it possible for authenticated attackers, with contributor-level access and above, to move/delete arbitrary local files via path traversal.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in muffingroup Betheme betheme allows DOM-Based XSS.This issue affects Betheme: from n/a through <= 28.2.

The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘page_title’ parameter in all versions up to, and including, 28.1.6 due to insufficient input sanitization and output escaping of theme breadcrumbs. 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.

The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via an Elementor display setting in all versions up to, and including, 28.1.3 due to insufficient input sanitization and output escaping. 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.

The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Button shortcode and Custom CSS field in all versions up to, and including, 28.0.3 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.

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.

The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 27.5.5 due to insufficient input sanitization and output escaping. 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 the SVG file.

The Betheme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 27.5.6 via deserialization of untrusted input of the 'mfn-page-items' post meta value. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via several of the plugin's shortcodes in all versions up to, and including, 27.5.6 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.
