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 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.

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.
