Wordfence advisory
medium · CVSS 6.1Several Smash Balloon Plugins for WordPress are vulnerable to Reflected Cross-Site Scripting via URLs in various versions due to insufficient input sanitization and output escaping with the use of add_query_arg. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

How do I check which product and version this report affects?
This report covers more than one product. Choose your plugin, theme or WordPress core in the version checker, then enter its installed version. Each product has its own affected ranges and fix details in the report above.
Which update should I install?

Does an affected version mean my website has been hacked?

Does a version outside these ranges mean my website is secure?
A version outside the reported ranges is not listed as affected by this particular issue. Other vulnerabilities, missing information or a previous compromise still need separate checks. Review other reports for your product and keep your website maintained.
