What the vulnerability does
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.
Explanation of Vulnerability in Simple Terms
Betheme versions up to 27.5.6 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users with low privileges to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users and site functionality. Site administrators should update to a version newer than 27.5.6 to remediate this issue.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect site functionality.
Potential impact on your site
Compromised user accounts, defaced content, or malware distribution to site visitors.
Conditions required to exploit
